Petr is excellent host, provided us with maps of Prague. Apartment is spacious and bright, much more beautiful than on photos. He was very modest describing his apartment on Airbnb. It's located 600 m from tram 22 stop. Tram 22 is all you need to go around historical part of Prague. Five stops from the center.
Apartment is in quiet neighbourhood, you can park in front of the building for free. Absolutely no hidden flaws, definitely would recommend staying in this apartment.
