Vadim's place is really nicely decorated and clean. It's quiet at night so you can get a good night sleep after walking everywhere around the city. Indeed, the place is walking distance from almost all the touristic sites, if you're not afraid of some walk. The bathroom and toilet are in the same room and also it's shared with two other rooms. Still, the bathroom is pretty clean and the host has a bath mat for each room so it feels cleaner.
There is one drawback: it was not easy to reach Vadim all the time by message and it was quite urgent at the time.
Otherwise, it was a good place to stay.
