We had a very good time in Kristina's place! We really feel in NYC in her flat and as if we were at home. The room hasn't any window but this is not a problem and we felt very comfortable.The bed is very comfortable.
As already said, the building could be refreshed but this is not really a problem.
Kristina is very nice and we had a great contact with her. We would come back with a great pleasure and without any hesitation.
