I think they do mean Casa Coral which is similar in name, also has three bedrooms and is just down the beach from us too. It is run by Caye Management. Thanks for thinking of us though.
I would recommend you book Casa Coral, and fast. It is well priced and one of only a handful of three bedroom beachfront homes within easy walking distance of town. It's in a quiet area, yet only a ten minute walk to town to the shops bars and restauarants. You get the whole of the third floor and the massive roof terrace. Two of the bedrooms are fairly small with single beds and this is the only potential slight drawback. Also Caye Managemnt are on the ground floor if you need them while there.
