Our visit to Prague was fantastic! Mark was prompt and very helpful. We stayed 4 nights. He showed us what all the keys were (easy to understand), went through his recommendations on things to do (which were helpful), and worked with us for our early train ride to Saltzburg. We loved the amount of space in the apartment and enjoyed looking out the window at the working Prague life (out of the sprays of tourists). Easy access to the trams, metro, and Wenceslas square. We used the Tesco grocery store (better than the Billa) which isn't far to pick up some odds-and-ends for food. Highly recommend both Prague and Mark's place!
