The place is rather nice and comfortable, although it was a little cold at night even with the air conditioner set on +30°С (we were there in November). Some extra blankets would have been nice.
The wine taps are a fun feature, but the wine itself is barely drinkable (fortunately, we expected this and bought some wine in a nearby shop). We only stayed for one night, so we didn't really use the kitchen, but I do agree with other commentators who said it could be better equipped. Bear this in mind if you intend to cook.
The location is easy to find and very convenient for exploring the old town. The only problem for some people could be the staircase, which is extremely steep and narrow.
The self check-in works perfectly, and the host gave us all the information promptly (although, as some of the other guests mentioned, the WiFi password he gives is in fact wrong).
All in all, we were quite happy with our stay. Thank you, Oliviero!
