I can't say enough about how great my stay was at Krste's place. Krste was extremely responsive and offered great local suggestions for my stay in Prague.
The apartment itself is centrally located. It's close to a number of local bars and restaurants but just far enough so there's no spillover with the noise. You can't ask for a better location.
With respect to the apartment itself, I believe that I was the first guest to stay here so everything was brand new. There were only 2 of us but realistically, four people could stay here pretty easily.
Highly recommend staying here if you can during your visit to Prague!
