I have a great recommendation for a hotel in Siem Reap. I stayed there for 7 nights over Christmas and New Year period and it was fantastic. The rooms were really comfortable and the service was excelent. It is based very close to Anchor Wat and this is a real benifit as taxis can end up costing more than you'd think. It was a cheap hotel for Siem Reap given the level of comfort and service, about 30$ a night. I would highly recommend this hotel.
