All perfect. The Flat is nice and it is 15 minutes away from the historical center of Prague.
You can reach it easily by walking and you have also the tram and bus stops at 50 meters from the flat, as alternative.
Pavel gives you a map and some tips for visiting the city. Also responds quickly at the messages and questions you could have. Check-in and Chek-our were easy and flexible too.
Highly recomendable for a trip to Prague.
