the flat itself is beautiful, just like in the pictures. However, it is located in an abandoned building, so while going up by the stairs you will see what looks like an abandoned hospital, really scary, I wouldn't have stayed here if I had children with me, we didn't feel safe. additionally, at 4am somebody decided to ring on the interphone of each room, it wasn't the hotel's fault though, but you should know that it could happen.
I think the hotel should upload pictures also of the way arriving to the rooms from the outside of the building, so everyone can have all the information and wether decide to stay there or not. We never used the elevator as it seemed lacking of maintenance, not safe.
On the other hand, they claim to be a contactless hotel but they take too long to answer the messages that has no sense. As soon as I arrived I let them know that the provided internet password wasn't working, we left the place (1 night) and I never got a reply.
Fortunately it was only one night, I wouldn't recommend to stay here.
