I rate this ad with five stars. First of all, Check-in easy, location good, room good, good communication, Polina helped us out on the check-out day.
There is one "but". There were no appropriate blankets for the season / temperature in the room. The heater worked, but was not hot enough (for us). So ask for extra blankets BEFORE check-in in winter.
All in all, recommended (read the paragraph above!). I still gave five stars because Polina was all in all extremely helpful.
