The apartment is really nice, we stayed there for a few nights and it was very comfortable and practical. It is located in the center so is very easy to walk everywhere but because of the tourism it can be a bit uncomfortable, specially at night.
The only thing with which I was not happy was with the communication, as I understand it is managed by a hostel and the only communication is by automatic messages, which is not really the spirit of Airbnb, and it is a problem when you have specific questions like wifi password. We never got it.
I read some comments that were complaining already about the communication so I hope it can change in the future.
