This hotel provides a solid value for those looking for an adventure base rather than a traditional resort experience. The views are absolutely stunning, and the basic rooms did the trick for our needs. However, the limited breakfast options and some staff interactions left a bit to be desired. Overall, if you're looking for a no-frills, budget-friendly place to rest between exploring, this could be a great choice.

I had a lovely stay at this resort spa, where the sound of the waves made for a peaceful night's sleep. The location right on the beach is fantastic, and I enjoyed the complimentary continental breakfast each morning. However, I found the dining options somewhat limited and could have used better variety. Also, while the staff was friendly, I felt the breakfast could use improvement with more choices available throughout the serving hours.

I had an overall good stay at the hotel for 4 nights. The room was spacious and clean, and despite the lack of air conditioning, we enjoyed a nice breeze by opening the windows. However, the breakfast was quite disappointing due to the unhealthy options and excessive waste produced from single-use plastics.

I enjoyed my stay at this resort, which has a stunning beachfront location and the rooms are clean and comfortable. The amenities like the pool were nice, and I loved the sunrise yoga sessions every morning. However, my initial experience was marred by an issue with bugs in my first room and the dining options were pretty limited. Overall, great value for the price though!
