Where You’re Staying

Each guestroom is individually designed with contemporary furnishings, coastal tones, and a view of the sea, harbor, or village. All include plush beds, handmade toiletries, and thoughtful comforts designed for unhurried stays.

Where to Dine

The Reef Knot Restaurant delivers seasonal menus rooted in local produce and fresh seafood. Set beside the water, the dining room offers relaxed elegance and panoramic views. Weather permitting, dine on the south-facing waterside terrace.

Where to Relax

Rejuvenate at the SEVAN Spa, where holistic treatments draw on ocean elements and natural botanicals. Guests can enjoy massages and facials in a serene setting overlooking the water. The peaceful setting and tranquil interiors make it easy to relax between coastal strolls or boat outings.
