My family stayed here (2 adults and 4 kids ages 9,6,4 and 2) and we had a great relaxing week. The house is exactly as described and really quite spacious. The rental rate is only slightly higher than the neighboring property with 13 units, but you get so much more at casa cielo (more space, private pool etc). A previous reviewer said the water pressure was low, but I didn't feel that it was inadequate at all. The onsite caretaker Lucio was readily available and very friendly. The house is on a property that is shared with another house. Casa Cielo is set back on the property, but from the pool and outdoor sitting area you can still see the ocean. As well it is protected from the ocean winds, which were gusting quite a bit when we were there.

The beach was good for the kids. There is a rock wall which holds the sandy area from washing away, and there is an easy entry area for when you want to go in the water. There were small waves while we were there, while the rest of the area was experiencing red flag days. We snorkeled in a few areas but found the snorkeling to be the best right at casa cielo. There is a gentle slope in the underwater terrain, and minimal current.

The house is just outside the town of san miguel which makes for quick drives into the city for dinner. There are a few restaurants within walking distance that serve standard mexican fare (tacos, quesadillas etc) and "american standards (burgers, fries etc).

Although the owner recommended renting a vehicle, I would suggest that if you are a big family, you should avoid renting a van. In the end we payed double the Expedia rate in canadian for the week. That is the most I have ever paid for a rental. We would not have paid nearly that much in taxis.

The island is set up for the cruise ships so a lot of places close at 5pm. In comparison to other places I have traveled in mexico (playa del carmen, akumal, puerto vallarta), I found cozumel to be on the more expensive side.
