I rate our stay positively, price–performance ratio is good. Apartment was clean, well equipped in very good location with shops and very close to metro. I would mention very cold floors (we stayed there in March) so I recommend to bring slippers. Apartment is not soundproofed, so you can hear metro under and (especially in the bedroom by entrance) your neighbors which is quite annoying. We had quite big problems to find apartment in building because there are no signs so I would recommend to ask specific info.
