Martin's apartment was just as described, warm and cozy in the freezing prague winter nights. My friend and I spent two nights there and couldn't be happier with our experience. We were warmly greeted by Martin and Petr who let us know everything we needed to about our stay and left us with breakfast essentials. The apartment is a short walk from the metro/tram/bus stop so getting around the city was very easy. I'll definitely be recommending Martin's place to all my friends.
