Well, the property is pretty fantastic, the rooms are very spacious and luxurious the bathrooms large and elegant. The environment is very peaceful and quiet (except for other guests) with a beautiful landscaped property. Please realize that despite a few activities (tennis courts, archery, kayaking) there isn't too much to do so it is more for rest and you are pretty far away from the hectic town center (there is a free shuttle with decent schedule to there). Didn't see a pool (but we weren't looking and the temperature is, even in summer, pretty cool. That's a good thing!).
The only problems were first, as I mentioned, other guests with noisy children disturbed the peace on our first day. They need to put in thicker glass in the windows. This is especially bad if you are on the first floor, also our first floor room didn't have much of a view (and we had to keep our blinds closed). Also, service was a little raw; the receptionist didn't understand when we asked for the electric cart to take us to the room (my Vietnamese gf asked in Vietnamese). Meeting the shuttle downtown was tricky because we hadn't taken it in and their directions to the stop were inaccurate despite several calls. However, after the first day, once we knew our way around things were fine.
All in all it made us feel like "a little New Zealand in Vietnam" :)
