We were staying in Olga's place for two nights and were absolutely satisfied with it! The room and a bathroom are authentic, the loft bed is very comfortable (especially thank you for the heavy blanket we had) and kitchen has all needed for a short stay. The inner yard is private and quite, both gate and doors have electronic locks.
The host is very helpful and responsive! We've forgot an important bottle of wine and Olga arranged the pick up afterwards with no problems.
The few drawbacks - it was pretty cold in the apartment on our arrival since the wall radiators where turned down and it took a while for the place to heat up when we turned them on. And the view out of the window is pretty plain, but in the morning we caught some sunrise light
