We stayed at Josef's place for a long weekend in Prague, and it was perfect for our stay. The apartment brings a whole new meaning to the phrase "centrally located". It is 50 meters from the famous Old Town Square on a pedestrian street that is lively during the day but quiet at night time (all nearby restaurants and shops close by 9 or 10pm). However, it is less than a 5 minute walk from the busiest part of the city. The apartment itself is simple, well equipped and clean. It is worth noting the apartment is small (hence better for 2 people and for short stays or for trips where you plan on spending a lot of time outside). There is no living room or dining room, although the bedroom is very large and has a couch and the kitchen has a bar with stools. Josef is very fast to respond and also sends local guides and gives local tips. The price is also incredible for what you get. Highly recommended.
