This was one of the best choices I could have made! The loft was very nice, quiet, perfectly well furnished, with sobriety and taste. It is quite central, with local bus stops a few steps away, a convenient supermarket, and simple restaurants. The windows open on a huge and quiet park, with a convenient path for pedestrians, also open to bicycles and roller-skates, that leads directly to the central train station (for instance) after a nice walk.
Petra was very kind and helpful, and the check-in/check-out process was perfectly smooth.
I strongly recommend this place, and I will remember it myself for my next trip to Prague!
