Martin's flat in Old Town is perfect! My girlfriend and I enjoyed the Christmas holiday in this lovely flat and were extremely impressed with all aspects of our visit.
Our host, Martin and Petr, was extremely welcoming. Petr was kind enough to pick us up from the Prague airport (for a very reasonable fee), and assisted us arrange transportation to return to the airport upon our departure.
The flat is beautiful and in an amazing location. The flat is just as described and more. The pictures are good, but the flat feels even more spacious and warm than can be seen. Surrounded by bars, clubs, restaurants, and other conveniences it is ideally situated. Additionally, the flat is a very convenient walking distance to the St. Charles bridge and other major landmarks of Prague.
Overall, the host exceeded our expectations and ensured a safe, charming and wonderful stay in Prague. I highly recommend Martin's flat to you.
