I stayed for one month in this flat while apartment-hunting when I moved to Prague. Loved the location, the super reliable wifi, lots of windows, and the big kitchen. The host was very quick to fix the shower drain when I discovered a problem with it on arrival, and it worked fine after--props for the fast, friendly, and effective response on that! Overall a good stay: safe, clean, warm.
Note: There are several Airbnbs in this building so it can be a bit rowdy at times overhead, sometimes to the wee hours.
