Josef is a fantastic host. He is super helpful with all potential problems. We stayed two month in his house. We had to prolong our our stay on short notice and he found a great solution and managed our change of flats without any problems. The house is located in a perfect position in the center of Prague. It is 5 minutes walk from the river bank and 15 minutes walk from Karlsbridge, There is tram and a bus stop in the square in front of it and the next subway station is only 5 minutes walk away. On the square is an entrance to one of the most beautiful parks in Prague (Petrin) and the surrounding blocks are full of restaurants. There is also a theater on the square. Besides being in such a central location it is however not overrun by tourists.
The flats in themselves are in an old art nouveau building. They are modern, beautiful, and very spacious. We felt very welcome and enjoyed our time there immensely.
