We really enjoyed our stay in Josefs apartment.
The location was brilliant just 2 minutes walk to the old town square and close to many other of Pragues attractions.
Josef was in touch prior to our visit to make sure all was ok and also very quick to respond to any of my messages.
Josef provided great tips on the attractions, where to eat, etc and regularly checked in to make sure all was going good during our visit.
I would highly recommend staying in Josefs apartment if you are looking to maximize you stay in Prague as the location is so good and Josef himself is so helpful.
