My third time staying at Dune, and it is just as good as it has always been. A small hotel, just 5 rooms,I think I have stayed in a different room each time and they are all excellent. This time I was in one, on the ground floor with it's own small plunge pool. All the comforts you would expect, and all working and in good order. Big pool next door for you to use, right on the beach. Two drawbacks, first there is no lift so anyone with mobility issues may have problems, though the staff are kind and always on hand to help. Second is the location which is about a mile from the main town, again no problem for me but if you are less mobile it can be quite a walk, you can ask for a taxi, as I did, but of course this comes at a cost, so maybe a factor if you are on budget.
If you are looking for a place to stay, this is the place, everything here is just perfect. Book with confidence, as there is nowhere better in Hua Hin...
