Pros (+) The location is convenient for anyone attending events at the Congress Centre, and it's also a close to Vysehrad Castle, and a short walk to either the metro or trams that run along the riverbank. The staff was, for the most part, very friendly (although the night time desk person was rarely inspired enough to utter much more than a grunt as a greeting.)
Cons (-) The bed seemed to be not much more than a glorified futon. It was quite stiff and lumpy. The shower is a tiny tube that has just enough room in it for a person to stand. Without any shelf to put soap or shampoo, this requires a cautious crouch to reach items on the floor of the shower, as there is not enough room to actually bend over.
