I brought my extended family here and rented the entire resort. I am not quite sure what capacity is, but we had 4 very large and well designed and furnished rooms and it certainly sleeps 8 easily. Naomi the owner is a doll. She anticipates your every need and her staff, housekeepers, gardeners, food service, and laundry help are just as lovely.
She has a Tuk-Tuk for your wandering needs and it is all lit up and wired for sound, and takes you anywhere you want--even Tonle Sap Lake which was a full day trip--for free--just tip the driver.
The pool is very large and kept at about 82 degrees--just perfectly refreshing w/o being cold at all. The beds, showers, furniture...everything, is just perfect. It was so much better than a hotel! Naomi and her driver both guide you to the best dining and shows and activities and warn you if something is too touristy. Breakfast is included and served on your schedule. We loved it and we would come back here again--or guide anyone we loved and care about to this place to stay in Siem Reap.
The A/C worked great and that is important in this region!
