Our party included two adult couples and two children 5 and under. The apartment itself provided a nice amount of space for all of us and the property amenities were excellent. It was very quiet the week we were there - felt like we had the whole place, including 3 pools, to ourselves. Antoine, the owner, was excellent - responded to all questions and minor requests without delay. The area itself offers a nice selection of Thai restaurants within a short walk - we especially like S Ken's, which is about a 15 minute walk from Las Tortugas. The beach was great - water was like bath water - and the kids really enjoyed swimming and searching for shells. Hua Hin city is about a 15 minute drive and worth checking out.
A couple of items that should be considered:
- there is a lack of kitchen utensils, pots and pans, etc. which is fine unless you prefer to do a lot of cooking
- the balcony rails are pretty open so people with small kids may find this less than ideal...
