My two friends and I stayed here for a few nights and for the most part it was just what we needed: a reasonably priced, clean apartment in a great location. I will give you a heads up on three things though:
(1) The internet is not good. It was very slow and only worked well at odd times of the day when others in the apartment building were not also online.
(2) There is no fan in the bathroom, meaning that the humidity from the shower has nowhere to go. Because it is a small apartment, it means that it can get quite stuffy. If you leave the windows open it's no problem, but we stayed in November, when it was a little too cold for that.
(3) The second sofa bed is very small. The three of us booked this place because it had three beds: one for each of us. However, the second sofa bed is roughly the size of a twin bed, so we were better off with two people sharing the large bed in the bedroom. Five people staying here would be quite cramped.
All in all though, it was a perfectly pleasant place. The hosts are very responsive and the whole process was very smooth.
