Seven Candles was a good choice for us. It is a budget accommodation, but the staff were very helpful, breakfast was reasonably priced and absolutely delicious, and the room came with a very useful guide to restaurants and other services in the area. I assume you'll be spending most of your time visiting the temples, but this is a comfortable spot to rest your head. Be sure to use the rooftop balcony - it's a pleasant place to relax and read. Book exchange, board games, and DVDs all available. The owners show a strong commitment to education for Cambodian children.
