This is a professionally run set up with several apartments across Prague - that has both upsides and downsides. The apartment was extremely clean and neat and their office close to the station is useful for storing luggage and coordination during the stay. The bad part was they charged us for a broken tap which was obviously broken before we took the flat. They would not consider that the tap could have been broken by the previous guest who in fact broke a chair while they were using the apartment. Otherwise the apartment is extremely centrally located and very good if you are focussed on old town and are using trains for your travel around Europe.
