Matt has a beautiful apartment and was a very good host - check in was in time and he provided very good and detailed directions to the apartment. We visited Prague in summer and due to the heat had to sleep with open windows which was a bit noisy from the street. I am however sure that this would not be a problem in winter as the windows are well isolated. The apartment is modern with lots of storage space and well equipped with everything you need. It is also centrally located with easy access to public transport,
