We got into Prague pretty late, but Josef was there to greet us and show us around. There was an extra set of keys which was nice, so that we could each have our own. There's a metro stop (and a Tesco) right around the corner which takes you into the Old Town, and the apartment was a 15-minute walk from the Prague Congress Center. The apartment was just as promised, and Josef was flexible with his time, which was very helpful to us. I recommend this apartment!
