We spent 4 nights at Dhevatara hotel at Praslin in November. The welcome was very friendly, our suite was clean, spacious, very new and well designed and the view from the room was indescribable. The staff was very helpful and friendly all time. The breakfast was a la carte, but it did not mean any disadvantage. The dinner served at the hotel restaurant was really delicious. The first day the beach in front of the hotel was full of seaweed, but it had just disappeared after 2 or 3 days, and it became a paradise like, long, white sand beach thereafter. So the best time to stay at this hotel certainly after the middle of November, because of the trade wind change and the seaweed condition. But if someone is planning to visit other beaches in the island or La Digue it no matters at all. My birthday was during of our stay, and the staff had realized that probably from my check in data, and had prepared a little birthday surprise in our suite, and a small birthday cake at dinner. Just a small courtesy. The complimentary bike hiring and the sea kayaking possibility is really good.
Overall, there is nothing wrong to say about this small, friendly boutique hotel, but if someone plans to spend the whole time at the beach in front of the hotel it is probably advised to travel from November to April.
