The hotel is nicely located about a mile from the centre of Siem Reap (2 USD by moto tuk tuk), so it was very quiet.
They can arrange a variety of tours to the Angkor temples (with or without a guide, half days, full days, sunrise, sunset, by car, van, tuk took, etc.). I don't know whether the prices are cheaper elsewhere but I found the total amount very reasonable, also considering it was hassle-free (booked at 10pm for the next morning!). Also, both the driver and the guide we got were extremely competent.
I was very impressed with the spa services.
The whole structure could use some maintenance work. The pool area was a bit run down and the pool itself didn't look super clean.
I emailed the hotel about guided tours to the Angkor temples and only got a reply three days later, when I was already staying there and had already arranged the tour with them face-to-face, so it was awkward to receive that response.
Breakfast was not a buffet, but a la carte with two complimentary options (plus coffee/tea and juice) - any extra had to be paid for separately. One day they forgot my request of a 4:30 am breakfast (they can arrange this on demand if you are booked for a sunrise tour), but they were quick to fix this and prepared a box with my breakfast to go.
The big windows are useless in the room located on ground floor (people ca see in your room unless you keep curtains pulled).
