We really enjoyed our stay at Katka her apartment during the Christmas holiday. It is conveniently located in a quiet neighbourhood but still nearby all the major sightseeing highlights of Prague. You walk to the Charles bridge within 20 minutes. There is a very large Tesco supermarket nearby and Katka recommended some excellent restaurants nearby (we tried Cafe Savoy and Olympia) and helped us with arranging a discounted taxi to the airport. The apartment itself is very nice, clean and has a great view over the city from the roof terrace.
