Very good

Liked: The staff was incredible from the welcoming lobby employees to the awesome fellow whom got us our kayaks. The employees were outstanding.The balcony was gorgeous!The room decor was beautiful! Nice to have all adult option.They had elevators that was nice! Felt very special there.
Disliked: The beds were a little bit uncomfortable. Maybe memory foam toppers could be added.Could not figure out the coffee machine, although it looked great. Maybe directions next to it would be great!The pool closed at sunset so was sad about that.

The most relaxed I have...

Liked: Amazing location. Beautiful beach area. Comfortable loungers round the pool. Relaxed laid back vibe . Friendly staff. Supermarket and bar within the property (land and sea) was excellent for breakfast . Complimentary kayaks.
Disliked: Nothing we didn’t like! Shower pressure wasn’t particularly strong/ but this might not be something that can be helped.

Beautiful, Clean and Comfortable

Liked: Clean and comfortable in an excellent location. Friendly and helpful staff.
Disliked: Very well kept and maintained property but the ice maker didn't work and the freezer didn't freeze well. Also the jetted tub is much higher than a normal tub. It had enclosed glass doors over it which made it difficult for older people to get in and out of.

Good

Liked: All rooms face the ocean and have a balcony.
Disliked: This time of year the seaweed was washed upon the shore. It was a lot and it smelled like seaweed. The resort tries to use a tractor to clean it out, but there is just too much of it.
