The rooms are way too small for four persons. There is no space to leave your luggage, no wardrobe, nothing! You have to store everything on the floor or in your bed. The roof top terrace was not usable during my stay. In only one week I even had to change rooms.
My card to open the door stopped working after three days, so I had to ring the doorbell in the middle of the night. Since nobody reacted, I was lucky to see some ppl hanging on the kitchen who could open the door.
I booked the cheapest option during winter, but it was still 20€ a night, so obviously, the lower price just does not exist!
I am very unhappy in this place, I wouldn’t recommend it.
