As no one has responded to date I will give you my 2 cents worth. My info is a little dated so may well have changed but it may well prompt others to post.
It is a newish hotel a popular place for young Thais heading to Hua Hin for the weekend. It had a very popular night club /disco.
If I were coming to Hua Hin I would not stay there simply because of its location which to me is too far out of the town to be practical. I think that there are better choices.
My personal favorite would be PP Villa.
I have lived in the condos at hin nam for 10 months or so. its a good deal for long term rental as its 5km out of town which makes it cheaper - you can get a songtaew for 10b though - if you rent for a year, you can get a 62sqm 2 bed 2 bath for around 12,000b a month plus bills.
