Make no mistake, Koh Samui is an excellent destination on many levels but our holiday was definitely enhanced as a result of basing ourselves (2 families w. 3 children) at Villa Horus.
If, like me, you fancy a bit of quiet-time with your family and friends (and a G&T) after your quad-biking / elephant riding / kayaking / diving with whale sharks / go-karting / shooting / temple touring etc. then look no further.
Max (the Manager) was easy to contact and is very competent; it was easy (and cost-effective) to arrange airport pick-up / drop-off, hire cars, tours etc. through him. The house was cleaned regularly, the pool was immaculate and the facilities (kitchen, bathrooms etc.) of a very high standard.
It is hidden away though, you will need transport to get to the beach; also, when you first venture out, I recommend having the guys at the gatehouse write the address / directions in Thai... Plus
