Martin offers the best of Airbnb. My wife and I stayed at his home, which is located on old town square across from Prague's famous astronomical clock. We stayed in his apartment for just over one week. It felt like staying at a friend's place who was out of town for the weekend, which is to say it had the conveniences of a lived in, cared for, and very clean home. We were concerned that it might be noisy, given the location, but the double windows (common throughout Prague) and the black out curtains made for excellent sleeping conditions. I'm a light sleeper and slept perfectly. I would warmly recommend Martin's home.
