I stayed at Dune for 5 nights in late September and come back very enthusiastically. This is a really nice hotel with spacious rooms and large bathrooms which are very, very clean. The rooms have all modern amenities, a huge flat screen tv, DVD, iPod dock and complete sound system with spekares in room, bathroom and balcony. The bathroom is modern and sleek and the hotel offers lots of bathroom supplies. The mini bar is well filled and replenished every day and two bottles of complimentary water are provided each day.
The staff of the hotel is a real asset, not always fluent in English but ever so helpful and charming. We were especially fond of the little cook, who went out of her way to make an omelette on our last day, outside the menu, and the leading lady in the restaurant, who was witty and dressed up each day and enticed us to try new cocktails each evening.
We ate in the hotel restaurant a few times and were very pleased with that as well. We tried some very interesting Thai and fusion dishes and all were really tasty, nice and spicy and freshly prepared. The restaurant/bar is available for non-hotel guests too.
On the roof terrace there is a little pool, but it's too small and awkwardly located to spend a day tanning. Instead the pool next door can be used. That pool is big and clean and there are hardly any other guests.
I would have given the hotel a 5 star rating if it weren't for some small inconveniences like a hard to regulate shower temperature, a small leak in the sink, some occasional clogging in the shower after heavy use and the music in the restaurant which could sometimes be heard on the 2nd floor. The blow from the A/C could be a little less too according to my taste, but most people enjoy it the other way around I think. All in all I would love to go back here and can recommend it to any traveller who does not need to be right in the centre of Hua Hin but close enough to be able to enjoy all town facilities.

I chose Dune because it claims that it is the design hotel, so that was pretty much what I set my expectation on. I stayed in deluxe room, room#2, and I can't find any bit of a design detail in the room! It's so simple and mainstream. So disappointed. Only the staircase and dinning/breakfast room that I found that there was a little of the effort in putting some uniqueness. But that's not enough for me though.
If you don't care much of a sea view, or even a walking-distant beach, private swimming pool, a wide range of breakfast, and most definitely, the design, you probaply consider Dune.

The boutique hotel details of this place do not disappoint. I loved the design down to the decore, furniture, and room set up. The large patio with comfy daybed and view of the ocean makes for wonderful lazy afternoons reading or daydreaming. The bathroom is larger than the sleeping area of the room -- with double shower head that felt like Westin's "heavenly shower", huge tube, and separate dressing / vanity area. The rooftop of the hotel is a cute bar / restaurant area with more daybeds another floor up. Also, the air-con works well and there are a couple cute cafes within walking distance.

The execution of this zen design sometimes lacks (the tub fills up so slowly, it took 1/2 hour to fill it quarter of the way up), the liquid hand soap smells wonderful, but the dispenser doesn't work, there's a TV with DVD player and stereo, but 1/2 the channels don't work (I was able to get CNN, BBC, and 1 - 2 English movie channels, but most other cable channels of interest to me were not functioning yet).

The food was great. I only ate there for breakfast, but it was substantial and well done. Eggs of your choice, fresh fruit, they offered salad when I said I didn't eat meat, fresh juice, coffee / tea, and breads. They also serve a warm muffin that tastes like a soft chocolate chip cookie...yum!

Except for the manager, the staff doesn't really speak English, but they attended to all my needs right away with some simple hand gesturing. The staff was charming really in their smiles, quick service, and overall desire to make my stay pleasant.

Would stay here again if the price is lower than the big luxury resorts. If it's in a similar range, you might get better value at one of those.
