Like everyone says, Josef is a great Host, no seriously he is. He gave us great recommendations on restaurants, bars, tourist spots and many more. I stayed at his place about 7 nights he checked in with me, time to time, to see how I was doing, and thats truly caring about his guest. Anyways about his apartment, just book it!! Best location in old town and all the best restaurants in Prague. I cant say enough how I am satisfied, if you are asking yourself should I book this, my answer is, just do it you wont regret it.
