I stayed there, alone and still had a great time. I only stayed 2 days but people where very nice and Roman who works there even nicer. OHH and the location is AMAZING ! you couldn't be more in the center.
The place is very clean, the dorm is big ( 10 beds ) but doesn't stink at all, and is also very clean. Bathroom is great, water pressure too, kitchen too, well everything is great ( and it's not always the case in Ukraine haha).
To top it all, I broke my shoe and wanted to have it fixed, he looks for me on the internet and everything was written on a paper on the door before I left.More
