This hotel was really lovely. The adults only pool and proximity to the water is amazing- the staff were friendly. I also like that the coffee opens at 6am.
The room was great and very clean with a spectacular view. The staff was extremely friendly and helpful. Housekeeping was great as well. We loved the pool area and beautiful views. We will definitely be back!
The property and room were spotless. Very pretty, kind staff, and amenities excellent! We stayed in The Conch House and had everything we needed. We felt very welcome. We had an excellent meal at the Rhum House and found what we needed at the market. We very much enjoyed a relaxing and beautiful vacation at Grassy Flats!
Clean, quiet and serene resort. If you're looking to relax and chill out completely then this is the place. The staff were all super nice and helpful. Absolutely gorgeous sunrise view. The property all around is beautiful. Our room was perfect and the views from the balcony were stunning! The food and drinks were excellent and the pool and hot tub were clean and relaxing. The store on the property was very well stocked and could cook up whatever you bought from them. Would highly recommend Grassy Flats resort.
Clean room, super hot jacuzzi, great margaritas, and amazing experience at the market. Due to beach clean-up, there was a bit of a foul odor, so didn't sit on balcony much, but great views when we did.
Excellent pet friendly property on the water! The staff were more than excellent! We thoroughly enjoyed our quick getaway and will definitely come back to this beautiful resort!

Beautiful resort with wonderful, friendly, accommodating staff. Food was outstanding with strong focus on fresh, local and organic choices. Definitely a great find!
We would 100% stay here again. We loved every minute of it. The staff, service, and property were top notch. The staff payed attention to little details and confirmed all information before we got there. They even had a 10 year anniversary card waiting for us. Very attentive and really appreciate the little things. Cannot wait to come back.
