Nikolai has a very nice apartment with spacious rooms and a nice kitchen. Check-in was fast and hassle free. We were there for a week.
He himself warns that there is a little noise in his house because it is at the intersection of two important avenues, a circumstance that is arranged with ear plugs (although there are windows that isolate the sound, sirens are still heard or noises strong, not missing at all). There is also something to cover your eyes because there are no blinds in the room. The bed is comfortable and the decor is simple but nice. The bathroom is spacious although it can be a bit uncomfortable to bathe because there is no curtain in the tub and it gets wet every time.
Otherwise, the location is fantastic whether you are walking or public transport and it is close to nice cafes and restaurants.
