If you are looking for a clean, affordable and well-situated place, you can stay at the Pichi Vimean Angkor Hotel. It is perfect for sharing a room as the double room only costs about 20 €. There is something very important for travels which is in-room wifi. Perhaps your weakness is in the breakfast which, although included, doesn´t offer much variety or choice. Breakfast includes an omelet, toast, milk and juice with no other possibility. In any case since it islocated about 5 minutes from the Old Market area, area restaurants, shops, pubs, etc., so that acts as compensation for the breakfast.
