Youth hotel. I don't know why, but there are a lot of young people. If you speak English or Czechoslovak, you will definitely find someone to talk to and maybe even make friends with. The staff knows Russian, which is an additional convenience when communicating. It's a long way from the metro, you need to additionally take a tram or bus.
There was a slightly unpleasant smell, probably from the bathroom, but generally barely noticeable. The sockets and lamps by the bed did not work, it turned out that it was necessary to get under it and plug just one plug into the outlet, but the receptionist did not know about it and could not help quickly. Otherwise, it is very decent for a low-cost airline
