Josef is an amazing host and the space was terrific! Located right in the center of Prague is was easy to get around on foot and by tram. Almost everything was within walking distance including the Castle. I found some great vegetarian restaurants (Traditional Prague food can be heavy on the meat and potatoes) and there is even a raw restaurant in the building, as well as a wine bar, a sushi bar, and a Vietnamese restaurant.
Not a view to speak of from the apartment but the light was really good and I was outside most of the time anyway. Truly a great place to stay!
