For our first experience in the Airbnb world, it was very positive ! Monika and Jaroslav were very kind, gave us very good advices about places to visit, restaurant where we can eat (and not eat). They also knew a lot about their city. We enkoyed our stay at their place !
Moreover they are in a very good spot, right in the center of the old Prague, 30 minutes from the airport.

Thanks guys for everything ! A place to stay in for sure !
