If you’re looking for a Hilton or some upscale hotel this isn’t it, but it’s still very nice. We had a large room with a balcony that opened up to an ocean front view (I believe all rooms have this). When you pull up it has more of a motel feel but the room was actually very nice, spacious and had a cozy island feel. It was easy to control the temp in the room and they were able to accommodate a pack and play for my baby which I really appreciated. Free breakfast is offered daily and you can walk across the street to Safeway, the drugstore, starbucks and other shops. It’s also walking distance from some local spots which was hugely convenient for us and we loved having the boardwalk from the beach to the Sheraton Hotel right next to us because we were attending a wedding there just a walk away. We would definitely stay here again.

Property is dated. AC was not working properly during my stay. Room was ok. Clean. But very basic. Small refrigerator. No wine glasses or any basic utensils. Breakfast was a joke, consists of fruit cups if any and apples No hot foods. No fresh baked goods. They could do better than this but they’ll probably raise their prices significantly if they do.

Our room was directly above the restaurant which played music every evening from 7 to 9 pm. We could sing along if we wanted to. We were not informed that our room offered this special benefit. The pillows were very firm or very lumpy. The television never worked. The air conditioner remained on continuously at a frigid temperature that the controls could not adjust. The location was great. Breakfast was adequate. Several staff members were helpful. However, we paid for paradise and received numerous torments to overcome.

A lot of bang for your buck. The property was so reasonably priced. The view is so beautiful. The hotel is older but clean and has a cute vibe. The only complaint is the beds are a little hard.

On an island so quaint and beautiful that has mega resorts, this small resort checks off so many boxes on my list: Clean - check. Oceanfront - check. Restuarant on site - check. Nice, clean pool - check. Comfy bed - check. Patio with chairs - check. Free parking - check. aT those other mega resorts, you may get a bunch of amenities and foo-foo stuff, but chances are unless you are going to break the bank, your room will be very far from the ocean, and far from all these amenities. This quiant hotel allows EVERY ROOM a view of the ocean, doesn't break the bank, and is centrally located. Would recommend this hotel to anyone!

ISO was so close to the ocean, you can walk to the ocean from ISO. The ocean view room was so great and amazing, the breezy was great. The pool was large one side is 8 ft deep. The sunrise was magnificent every morning. Shopping is one block away by walking or driving. Very quiet and relaxing.

Nice swimming pool and firepit, lounge chairs on lawn oceanside, onsite restaurant and lots of nearby dining and shopping, great walking/bike path with bikes available at the hotel, good 'grab and go' breakfast with tables available if you wanted to eat there. Small refrigerator in room, no microwave.

Likes: ocean view from the rooms, centrally located between North and South points of interest on the island, proximity to shopping and eateries. Dislikes: only restaurant on grounds opens late afternoon, pool needs better lighting and repairs, hotel is old and dated. We made reservations 2 months in advance for our honeymoon for a weeks stay and a special request for ground level room and king sized bed (which we specifically reserved), and were ignored. We were instead told to "just push the 2 full sized beds together" on our 2nd floor room. I overheard other guests with similar concerns which were also ignored in favor of other guests staying shorter periods of time. Even after requesting a room change the next day and explaining my wife's difficulty going up stairs, we were told that we could move to the 3rd floor room with a king sized bed or stay in our current room. The lack of consideration for special requests and customer service has lots of room for improvement.
