Martin is a wonderful host. He was waiting for us in the apartment for the check in. For our questions he always responde really quickly and provided lots of local tips. The apartment is really spacious and clean, the location is the greatest, right next to the astronomic clock in the old town square. We could have saw the clock and the church right from the window view. The windows are really sound proof keeps you away from all the noise outside. I really recommend to stay with Martin in Prague, book this place without thinking twice if it is available, you will NOT regret!!
