Anna & Petr are amazing hosts. Right from the get go, Anna was very communicative and patient to answer our queries. My wife and I stayed at their place for 4 days and nights on our first visit to Prague. And tbh we couldn't have chosen a better place to stay. It was cosy like a home and located right in the heart of mala strana neighborhood - one street off the main road that leads to Charles bridge. This gave the neighborhood a slightly less touristy and more homey feel despite being at a 5 mins walking distance from two of the most visited attractionsin Prague - the Prazsky hrad and Karluv most! About 2 & 5mins away are tram and metro stops that basically will connect you to anywhere in the city.
Since it was kind of hot when we went, we'd leave the magnificent windows open at night - this meant ambient sounds of the neighborhood wafted in - could be a problem for light sleepers but we were usually pretty exhausted after and liked waking up to the sound of bells of St.Vitus!
All in all, we know where to stay on our next trip to Prague!
