We stayed at Casa Calypso for 9 nights in February 2014, with two families. This is a spacious home directly on the beach. The home is located about 20 minutes outside of Progreso, between Uaymitun and San Benito. The location was convenient for accessing some of the local sights, such as Xcambo ruins or San Crisanto mangrove tour (highly recommended). We also made day trips to the La Ruta Puuc and Uxmal, a bit further.
The home itself easily accommodated our two families and had a pool right on the back patio. It also has a palapa out back with two hammocks and second story loft that is great for kids. It's a great beach for swimming as there are no rocks and plenty of sand.
You deal directly with the owner of the home which is a benefit. The communication was quick and we had a few requests that were accommodated before we arrived. The owners met us at the home and walked us through, they remained in contact if we required anything. There is also a caretaker in close proximity if anything is required.
Both our families thoroughly enjoyed our stay and would recommend this home for a quiet and relaxing beachfront stay.
