Mark and Marcela are very friendly people. We arrived very late due to our flight, but Mark was still up to give us the key to the room. Furthermore, everything is very clean (it gets cleaned often) and the location is great (15 minute walk to city center, and great connection with tram). You should be aware that the appartment is 6 levels up, so if you have trouble with walking, this is probably not a good idea. Other than that, this room is perfect!
