My property is still un bookable

Hello my name is Xheladin Toro. My situation is that I have rent a property and I am trying to listing to booking with the name Hostel New Rose that now booking say that is  un bookable. Attached you will find the contract that I am the new renter of the hostel that is in the building at C/Esglesia, nr 7, 17130, L'Escala,(Girona). The problem is that our page appears un bookable and the older owner of this hostel with name "Hostel El Roser 1" in booking, continues with reservations and the clients pay for the rooms that doest exists, they come to us and complain also they report to booking. Please if it is possible to let us un appointment in your offices in Barcelona to solve this problem because it cause us many trouble, apart that we are losing many every day! The Hostel with the name "Hostel El Roser 1" must be closed and our page is "Hostal New Rosé" that needed to be bookable.

Waiting for your response and solutions !First page of contrat
