Olena was very nice to me. She made an effort to hand over the keys so that both of us would be more flexible in terms of the check-in and was very helpful giving advice on Vienna, always reachable by WhatsApp.
The room is simple and part of a large shared flat. The person I met was very nice too.
The tap in the bathroom could do with some fixing, but otherwise it was all that I needed, for a very reasonable price.
