“Lovely hotel but lacking in nearby restaurants”
Lovely location but very remote Nice pool and beach ,although lots of seaweed so not able to go in the water TV didn’t work despite asking and someone looking at it but never resolved Really poor service at the Rhum House ,nice food but rude staff who ignored us so we left and then text us to demand us to come back for payment ! Thankfully the lovely lady on front of house (who is leaving) adjusted our bill to reflect the poor service

“Relaxed, luxurious break with great sports and views”
Following a long drive we received a great welcome from Morgan on reception, who eased us into the Grassy Flats vibe. The room (302) was outstanding, shotgun style, with 2 great Queen beds, plenty of space, good quality furnishings and clean. The bathroom was superb, 2 wash basins, a super large shower with built in seat, and then the balcony. A tremendous view so peaceful and relaxing. We ate breakfast from the diner on the balcony each day and the food was excellent
