What an amazing hotel. Lovely rooms that are meticulously cleaned each day and given the turn-down service at night. Fantastic food, not only the sumptuous breakfast buffet that's included, but also the lunches and dinners a la carte - all served by friendly, smiling staff. Oh and then a cocktail bar with a glorious view to start or end the night. Cannot fault it.

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!

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

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
