We had a little delay, but due to the great communication with the host there was no problem. Free parking is availaible near the apartment, which was clean and offered anything you need. The tram station was located 3-4 minutes (walking) away and two lines will pick you up about every 5 minutes & bring you direct to the city centre.
We had a great weekend in Prague and were more than satisfied with the apartment and the overall procedure. I would certainly book the apartment again.
