Stayed here just last week, the hotel and facilities are great. I stayed in a deluxe studio room with the mrs. The room was massive, I was a little apprehensive before going as a studio apartment in a Europe normally means your getting a shoebox sized apartment with a bed, a worktop complete with kettle and microwave and a tiny toilet. This room was not like that at all, it had a king size bed, a kitchen which is bigger than the one in my house which was kitted out with everything you'd need, a dining area and even had a sitting area with couch, coffee table and chairs. We had a Seaview and a balcony. The room was kept clean and tidy, so no complaints.
In fairness I never actually used any facilities at the hotel, I had a car so always travelled elsewhere to see the island, I was only here for a week so wanted to do and see as much as I could and not just lie round the pool. However I did walk around the hotel, it's got everything you need, 5 pools of varying sizes located all over the hotel (this hotel covers a large area), a good sized gym with plenty of machines, resteraunt and a casino all on the grounds, and a nice beach with beach bar etc.
To sum up, I'd recommend this hotel and will stay here next time I holiday in St Martin.
