Josef and his apartment in Prague was the best AirBNB we stayed at in Europe on our month long trip.
It is located in the heart of Old Town on one of the oldest streets, it is well appointed with modern comfortable beds, has a great shower, a kitchenette and table area and Josef was very prompt with everything. He even agreed to print some online tickets for us and delivered them right to us. That was after providing a lot of tips on touring the city and communicating well with us.
One Note: When you check in, just know the apartment entrance, or at least the stairs leading up to it are in the mini market. It's no big deal at all, actually quite cool once you know.
