I visited the Sand Castle, but did not stay there, about 4 years ago. It was a little isolated...too far to walk to town or the lovely beache4s of Sosua. There was an unattractive beach below the cliff but creek by emptied into it...the creek looked like it carried sewage . I hope it is now cleaned up. A lovely hotel in Sosua is Sosua by the Sea...there are lots of good hotels in Sosua all walking distance to the beautiful beaches. Something else road into Sand Castle is gated so local people around...not my kind of place.
