It was a great experience to stay at this magical place, hosted by Jakub and Boris. First of all, Jakub was there to help us with the parking as we were terribly tired from the trip. Then he showed us the place, our rooms and a map with all, literally, all places one may want to visit. The apartment is a designer's loft, with roof windows, terrace and a fire place. Cozy, comfortable, all necessary things at hand.
In the area there are a lot of bars and it's walking distance (well, it was for us) from the city center. And public transport is not expensive in Prague anyway.
So overall, from all places in Prague I would recommend this one!
Thank you guys for making us feel welcome :)
