We stayed here for 5 nights in July and it was amazing! The hotel is beautiful, the images online do not do it justice. It is quiet, and even in peak season was not super busy. The staff are lovely, and food and drinks are amazing. We were upgraded which was a suprise and the swim up rooms were incredible. We will definitely be staying here again! Thank you!

Great hotel with lovely design features. Our initial rooms aircon unit had a fixed temperature so it was like an oven at night. In such hot conditions this wasn’t great - especially when they told us the technician had fixed it and it couldn’t be amended. Only to find out that other guests could control their desired temperature. After 2 nights we had to say something and they changed our room. Everyone comments on the lack of umbrellas by the pool and it’s true - it’s ridiculous and I dont understand why they don’t do anything to resolve it. The only other challenge he is there’s nowhere for guests to shower if you have a late flight. Other than that we had a great stay. Great staff and beautiful views etc

I liked the hotel and the layout, the pool area, is very good looking, the average age of the people staying there is probably late 50's to mid 60's so you can be pretty much be assured that you won't get a football or a frisbee flying across the pool area, there is a beach near the hotel where you can watch the sunset called Makris beach. The WiFi in the room was very temperamental, the actual rooms are very very good looking apart from the front door to each room, which is strange, if they were to be changed then that would be a great bonus. George at the bar by the pool is brilliant along with the staff there and the staff at the bar in the front by reception, I can't fault any of the staff and there are too many to mention, but they were all great!

Lovely hotel and very friendly staff. Only issue which put a dampner on things at the start was a sea view room ( for which we prepaid ) was not available on arrival so wd had to settle for a different room for first night. This was happening a lot with new arrivals and some rooms are lovely but others very dated so not all as per lively pictures. Probably the most expensive hotel in the area but a little overpriced although staff were really nice Pool area bar really nice but a 10 min walk into Lassi and everything at least half the price
