Our family of four (parents plus girls of 19 and 22) have just returned from the Centara. We chose this hotel because of its location, we have been to Hua Hin before but stayed outside the town, for us this is a mistake, we like to be able to walk into the town, have a drink and a meal, look at a temple, go to the night market etc.
In our view there is nothing in Hua Hin to compare. We do not like large hotels and do not like high rise, the Centara is low rise, is not large by Far East standards and has great grounds. The service in the Centara is excellent, as good as the best that we have stayed in in the Far East, much better than Africa, U.S, Europe. The rooms are fine (Superior) but not fantastic. The grounds are a real treat, but more than anything we came away feeling that the staff (all of them, the sunbed men, cleaners, reception staff) are all excellent, always helpful, not obsequeous.
The town is great a good mix of restaurants, bars, night market. I am sure we will go back.
