What an interesting and great apartment! This is what makes airbnb so cool, as you wouldn't expect this kind of accommodation at a hotel or anything. The unique and artsy style is very cool (and the place is full of Roman's art), and although unorthodox, it was comfortable enough.
We were in good communication with Roman and we checked in no problem. It's not that close to the city, but it's very close to a tram station. The lack of wifi was slightly inconvenient, but that was mentioned -- and the bar across the street has wifi, so just go get a pint.
The apartment has a lot of really old and stubborn locks though.
