Amazing place!!
A friend of Zsofi picke us up directly at the train platform and guided us to the apartment, although it was pretty easy to find. She also explained a lot to us about Prag, where to eat, go out, sightseeing, everything ;-).
The flat was really great! It was clean and central. Everything we needed was there, even more. They had some beer and wine for us in the fridge.
It was the perfect place to walk everywhere in Prag.
I only can recommend this place. :-)
