My first room was very old, air con went off during the night, so it went pretty hot in the room during the night. Mini bar / fridge didn't work at all. The room had no window to outside, only to the corridor, so that you could never really open the curtains. No wi-fi in that room, therefore I had to go downstairs. That room was a mess,, but I got another one.
The rooms are VERY different, my second one was pretty new, air con worked, mini bar / fridge was also cold - both was not the case in the room they gave me first.
Breakfast was good, so far the best I had in Cambodia, wide choice and they were fast in filling it up. They offer breakfast for take away, if you leave early (for sunrise at the temples). Most of the staff was friendly and helpful.
