After viewing many pictures and reading other reviews of Su Casa, my now-husband and I decided to honeymoon there. Unfortunately, our stay coincided with Hurricane Dean, which I'm sure contributed to the many problems we had during our stay. First, the property is owned by an American couple, but actually managed by a Mexican family who speak little English; all communication is done through the couple in New York. We were told that "Marco" would be there to meet us, and was aware that we would be arriving late. However, "Marco" and his family had already evacuated the island in preparation for the hurricane when we arrived, but no one thought it necessary to tell us that. After spending $15 to cross over to Isla Mujeres, we were left stranded at an empty property miles from the main port and quite far from other hotels, in the dark, with a storm approaching. Days later, after the storm had come through, we were unable to make contact with the owners in the United States, and after many, many attempts, finally touched base with "Marco." We intended on staying at a nearby hotel for the reaminder of our trip, because we were so turned off by our initial experience at Su Casa, and because the hotel had a pool, but were told that we would be unable to recover our deposit. We spent two nights at Su Casa, and were still disappointed. The cottages are very basic, and ours was not at all clean. The family in charge was not often there, and we had a hard time obtaining toilet paper and towels. The beach was a mess as a result of the hurricane, almost entirely covered in debris, but no one started to clean it up until the day we left. There are also stray animals that roam the area, including two specific cats and a large pit bull (who actually may belong to the managing family, as he seemed to be "guarding" the property, but who was never treated like a pet in front of us). Be aware that these animals will come right up to your patio and try to get inside your cottage. There are also very large iguanas that live immediately outside the cottages, and who are not afraid of humans, in addition to the many small lizards and large roaches we found inside the cottage itself.
As I said, I understand that many of the problems were likely the result of, or exacerbated by, Hurricane Dean. That being said, we would have appreciated a little more accommodation and at least the appearance that Su Casa wanted us there as guests. If you are not a very outdoors-y person, and do not speak any Spanish, I definitely would advise against Su Casa.
