The room is really big. We arrive at 13:30 because the bus has a one hour delay but he made everything to receive us. He explain us how to move in Prague, places to visit, even hot to get the train tickets to kutna hora.
The bathroom is one of the best that we get in Airbnb. He also left for us 3 cold beers in the fridge.
The apartment is near to the center and in a quiet zone, super clean and very luminous in the day.
Thanks for all David!
