Daniel responded super quickly to all messages & looked to help us with everything we needed. We didn't actually meet him in person, but there were other friendly people who work with him, who welcomed us & assisted us later when we had questions.
The place is simple & clean, perfect as a basis for explorations of the Stare Mesto & beyond. There is also a little kitchen (clean & good as well) that you share with the other guests in the other rooms of the flat. A few basic things like coffee are provided there.
There was no real contact with the other guests, as I feel everyone comes with a kind of anonymous hotel mentality, but of course that has nothing to do with the host or the place, it's just the way it is it seems.
