Terms & Conditions
Stay Sunday
Effective date: 18. July 2025
1. Scope and contracting parties
1.1 These General Terms and Conditions (hereinafter “Terms” or “GTC”) apply to all contracts for the temporary rental of apartments and hotel rooms for accommodation concluded between Bay One Hospitality Group AG, Hauptstrasse 30, 8268 Mannenbach-Salenstein (hereinafter “Stay Sunday”) and third parties (hereinafter the “Guest”), as well as to all additional services and supplies provided by Stay Sunday (together, the “Accommodation Agreement”).
1.2 These GTC apply exclusively. Any general terms and conditions of the Guest that deviate from, conflict with, or supplement these GTC shall only become part of the contract if Stay Sunday has expressly agreed to their application.
1.3 Any GTC of the Guest are not recognised and shall apply only where expressly agreed in advance between the parties.
2. Conclusion of contract
2.1 The contracting parties are Stay Sunday and the Guest. By making a booking for one or more apartments or rooms, and any additional services, an Accommodation Agreement is formed. If the booked apartment is available, the Guest will receive a reservation confirmation from Stay Sunday. Upon Stay Sunday’s acceptance of the Guest’s reservation, an Accommodation Agreement comes into existence between Stay Sunday and the Guest.
2.2 If a third party has booked on behalf of the Guest, such third party shall be jointly and severally liable to Stay Sunday together with the Guest for all obligations under the Accommodation Agreement, provided that Stay Sunday has received a corresponding declaration from such third party.
2.3 The minimum age for a Guest making a booking is 18 years. Minors are not permitted to stay in an apartment without an adult legal guardian.
2.4 Offers by Stay Sunday concerning available apartments are without obligation and non-binding. Stay Sunday may, at its sole discretion, decline to enter into an Accommodation Agreement.
2.5 There is no entitlement to accommodation in a specific apartment. Stay Sunday reserves the right to define industry-standard restrictions for certain dates, such as minimum stays, booking guarantees, or deposits.
3. Cancellation and no-show
3.1 A reservation is deemed “guaranteed” once payment by the Guest has been received by Stay Sunday. A guaranteed reservation may be cancelled by the Guest in accordance with the cancellation policy stated by Stay Sunday and upon providing the reservation number, unless the Guest has chosen a non-refundable rate.
3.2 A cancellation means the apartment is no longer reserved for the Guest and the Guest is entitled to a refund of amounts already paid. The Guest’s entitlement to a refund lapses if the Guest fails to cancel by the deadline agreed with Stay Sunday and shown in the booking.
3.3 After expiry of the cancellation period, cancellation by the Guest is excluded. Stay Sunday retains the claim to the agreed remuneration—despite non-utilisation of the service—less any saved expenses.
3.4 Stay Sunday also retains the claim to the agreed remuneration in the event of the Guest’s no-show or early departure.
3.5 In the case of multi-day guaranteed reservations, in a no-show scenario Stay Sunday not only retains the claim to the agreed remuneration, but also reserves the right to release the apartment for all subsequent nights as from (and including) the second night.
3.6 A Guest who has already checked into the apartment on the arrival day loses the right to cancel free of charge upon check-in.
3.7 For bookings of five or more apartments (“Group Bookings”), cancellation is possible up to eight (8) weeks before arrival. If the Guest withdraws up to four (4) weeks before arrival, Stay Sunday is entitled to charge 50% of all reserved services. If the Guest withdraws at a later point in time, Stay Sunday is entitled to charge 100% of all reserved services.
3.8 For bookings made via third-party providers, cancellations may only be made in accordance with the terms agreed between the Guest and such provider.
4. Accommodation rates and other prices
4.1 The prices displayed by Stay Sunday at the time the contract is concluded shall apply. The applicable prices are gross total prices and include all statutory taxes, fees, and charges.
4.2 Local charges which, under applicable law, are owed by the Guest (e.g., city/bed taxes) are not included and will be charged separately.
4.3 In the event of changes to tax, fee, or charge rates, or the effective introduction of new taxes, fees, or charges, Stay Sunday reserves the right to adjust prices accordingly. In contracts with consumers, this applies only if the period between contract conclusion and price adjustment exceeds four months.
4.4 Stay Sunday may make its consent to any subsequent reduction requested by the Guest in the number of booked apartments or in the length of stay conditional upon an increase in the daily rate due to the shorter rental period or reduced rental volume.
5. Payment terms
5.1 The price for the entire booked accommodation service must always be paid by the Guest in advance.
5.2 The Guest is not entitled to set off claims, unless the set-off concerns an undisputed or finally adjudicated claim.
5.3 Accepted means of payment are Mastercard and Visa. Cash payments are excluded.
5.4 The reference date for payments in foreign currencies is the date on which payment is received by Stay Sunday. In the event of a refund, this same reference date applies.
5.5 For fees incurred subsequently due to additional services used or breaches of these GTC, Stay Sunday reserves the right to charge the outstanding amounts to the stored payment method.
5.6 Invoices issued by Stay Sunday without a due date are payable immediately upon receipt without deduction.
5.7 Stay Sunday is entitled to declare accrued claims due at any time and to demand immediate payment. In the event of default, Stay Sunday is entitled to charge the applicable statutory default interest.
6. Use of reserved apartments
6.1 A reserved apartment is available to the Guest from 15:00 on the arrival day and until 11:00 on the departure day. The Guest has no entitlement to earlier provision on the arrival day or extended provision on the departure day.
6.2 Unless otherwise agreed, any keys and, where applicable, key cards provided on the agreed departure day must be returned to Stay Sunday or a designated third party or, if agreed, left in the apartment.
6.3 A later departure (“Late Check-out”) may be agreed with Stay Sunday in advance upon request and subject to availability. If Stay Sunday consents to a late check-out, Stay Sunday is entitled to charge a fee for the additional use of the apartment. For departures after 14:00, the full current daily rate is charged.
6.4 If the Guest fails to vacate the apartment by 11:00 at the latest, Stay Sunday may charge 50% of the full current daily rate for late vacating up to 14:00 and 100% thereafter.
6.5 An earlier arrival (“Early Check-in”) may be agreed with Stay Sunday in advance upon request and subject to availability. If Stay Sunday consents to an early check-in, Stay Sunday is entitled to charge a fee for the additional use of the apartment.
7. Resale and improper use
7.1 The resale/subletting and/or onward brokerage of booked apartments is expressly prohibited. In particular, onward brokerage of apartments and/or apartment allotments to third parties at prices higher than the actual apartment prices is not permitted.
7.2 The assignment or sale of claims against Stay Sunday is also not permitted. In such cases, Stay Sunday is entitled to cancel the booking.

8.2 In cases of simple negligence, Stay Sunday shall be liable only for the contract-typical, foreseeable damage and only insofar as a duty has been breached the fulfilment of which enables the proper performance of the Accommodation Agreement in the first place (a “cardinal duty”).
8.3 Should disruptions or defects occur in the services of Stay Sunday, Stay Sunday will, upon becoming aware of them or upon the Guest’s prompt notification, endeavour to remedy them.
8.4 Liability for items brought into the apartment is governed by the statutory provisions. Any claim lapses if the Guest fails to notify Stay Sunday without undue delay after obtaining knowledge of loss, destruction, or damage.
8.5 If the Guest brings money, securities, and valuables with a value exceeding CHF 1,000 into the apartment, Stay Sunday’s liability is limited to the aforementioned amount. For other items with a value exceeding CHF 4,000, liability is limited to one hundred times the price of the booked apartment for one day, but not exceeding CHF 4,000.
8.6 If a parking space is provided to the Guest, no contract of safekeeping is created thereby. There is no duty of supervision. In the event of loss or damage, Stay Sunday is liable only in cases of intent or gross negligence on its part.
8.7 All claims against Stay Sunday shall become time-barred within one year from the statutory commencement of the limitation period. This does not apply to claims for damages arising from injury to life, body, or health; the statutory limitation period applies to such claims.
