Jan is very good to communicate with. He responds quickly to emails, and arranged to come to the apartment at 7am to meet us. The apartment is in a good location- it's on a main street about 1 block from the metro station and one block from Charles Bridge.
The apartment is very small, probably better for one person than for two. The sheets, sink and toilet are clean but everything else could be a bit cleaner. Overall it was ok for a short stay.
