At Grassy Flats Resort & Beach Club, travellers consistently praise the friendly staff, serene atmosphere, and stunning ocean views, with many enjoying the adult-only and family pools, on‑site dining, and easy access to paddleboards, kayaks, and water activities.
Rooms are generally spacious and beautifully decorated with great views, though some older units feel dated, a few beds are uncomfortable, and occasional AC or maintenance issues are noted. The beach is scenic but often less swimmable, and recurring seaweed at low tide can cause strong odors. Dining is widely enjoyed at the restaurant, market, and bars, but options or hours can be limited at times and prices can feel high. Expect a relaxed, well-kept boutique resort with standout service.

Quiet, secluded feel with beautiful ocean outlooks, and many find the mid‑Keys location convenient for day trips. A car is useful; some guests felt it was a bit remote and the natural beach is more for relaxing than swimming.
