The general experience was positive. Andrei explained us how to reach the apartment and meet his father at the closeby studio. The flat was warm and clean. The bathroom had been cleaned and we were provided fresh towels and linen. All in all, the only thing that disappointed us a little was the kitchen: there were few kitchen tools (only one small pot, no microwave) and some dishes and forks were not clean. Furthermore the cleaning in the kitchen zone could have been done better (some cobwebs) and one of the walls starts to be consumed by humidity.
The location is great, close to metro in a quiet zone with a pedestrian shopping street nearby. the apartment is on ground floor with a big window facing the street (the flat was a barber shop once) but at night the street is quiet and very hardly you will be disturbed by passersby. Just bring an eye mask if morning light might disturb you
