Loved it. I come from 100+ degree state and to vacation in 76 degree weather during the summer month, it’s just too great. The hotel is close to what I needed on a vacation - food, drinks, and a chilling atmosphere.

I was very happy to see that I could check in several hours earlier when I arrived. Was also given an hour later check out. Chose this hotel as it is near the airport did not expect all the wonderful restaurants, amenities of hotel and seaside restaurants. The room opened very nicely for a view of the ocean. When I arrive, the room was quite warm and I was told there’s no air conditioning at this time of the season to open my window and let the wind come in. it’s certainly helped. Night for sleeping with window open was very comfortable. I recommend this hotel for anyone wanting a beach experience in 20 minute ride to the terminal two airport. Receptionist was very kind accommodating spoke English very well.

안내 메시지로 꼼꼼히 입실 준비까지 대응 빠르고 친절합니다. 전망 좋네요. 안내 메시지는 받았지만 호텔명이 예약 시 이름이 건물을 통해 인지할 수 없어서 메시지를 무심히 넘겼다가 당황할 수 있습니다. 사용 수건에서 그늘에서 말린 냄새가 남아있는게 흠이었습니다.
