The flat is exactly as depicted in Airbnb. Very comfortable, and cozy. We felt like at home from the very first moment. There's a great book collection, vinyl records and cds that made our stay even lovelier. We didn't use the kitchen or the apartment's supplies (other than the bathroom), since we were all day out, but you could tell it was fully equiped.
The only "con" is the bathtap that has a really low ceiling and it's impossible to take a shower standing up. Other than that the area is perfect, the wi-fi works better than mine, and the heater kept us warm from the outside!
We couldn't met Roman, although he was really kind giving us advice, recomendations and constant and fluid comunication via Airbnb. The guys from the bookshop helped us a lot, gave us maps, instructions and recomendations.
We highly recommend Roman's apartment.
