The contract becomes valid when the Hotel accepts the customer’s application. If the Hotel makes the customer a firm offer, then the contract takes effect with the customer’s acceptance of the Hotel’s offer. Room bookings should be confirmed in writing.
The contracting parties are the Hotel and the customer. If a third party has placed a reservation on behalf of the customer, the customer and the third party shall be jointly liable to the Hotel for all obligations arising from the Hotel Accommodation Contract, insofar as the third party shall provide the Hotel with an appropriate statement to this effect.
