Although I did not get to meet Andrey in person, the host was very communicative and kind. I received a concise/visual instruction for check in and out.
The best thing about this airBnB is the location in the heart of Old Town. My stay was very short (2 nights). Thanks to its location, I was able to dine at great restaurants and enjoy the beautiful parks and historic sights. The location was perfect for a first time visitor like myself. There's a convenience store right downstairs too.
This AirBnB had multiple stages of doors/securities to get to the room, which made a solo female traveller like myself feel very secure.
There were challenges however. No elevator to the 3rd floor, and the staircases are narrow and steps are tiny, especially if you must carry heavy luggages. I'm originally from Japan and I am used to such small spaces. I consider myself to be healthy but this was still a challenge for me. The entire place was smaller than my studio apartment I once had in NYC. There was no TV or AC. The host left a fan but the room was warmer than outside. You'd have to clime to a bed and it wasn't easiest for me. None of which were problem to me but if you have any type of physical challenges or difficulties, I would not recommend this place. I can see this is an amazing place for a very healthy person who wants to enjoy their Old Town scenes.
