This hotel has limited check-in hours. In the event, you miss the check-in window, walk into the hotel door, open the door on your left and walk into the restaurant which will be empty. Continue walking and on the right hand side there will be a table that likely has a key card for your room. If you continue walking further back within the restaurant, there is an elevator on the right hand side past the bathrooms. This hotel is fantastic, Maria is very friendly and helpful. The breakfast is amazing so given the opportunity to include it in your stay, I would highly recommend though it is still available for purchase. This is located near many sites and very walkable to shops, restaurants and other things. We would stay here again.
Keep in mind hotels in Europe do not have conditioner or wash clothes so come prepared.
