The place is exactly as described and Jose Luis is incredibly honest about telling you the shortcomings of the place, so your experience will be as expected.
Anything you need in the room Jose Luis will supply promptly, his lovely sister might be the one you see, but the experience is excellent.
If you want to be in Polanco half a block from supermarket and metro station, 5 blocks from the center of Polanco with all it's restaurants and Lincoln Park, this would be your little place.
