There is no shortage of accommodation in Phnom Penh, with an increasing number of guesthouses and hotels across the city catering for all pockets and tastes, from basic rooms with fans to opulent colonial suites with every luxury. No matter when you arrive, you should have no difficulty finding a room, although it's no surprise that the very cheapest room fill up quickly. Arriving in the morning stands you have a better chance of getting really inexpensive accommodation, as many people check out early to catch onward transport. If you intent to stay for more than a couple of nights it's worth asking about getting a discount at guesthouses and mid-range places.

If you're on a short pocket travelling and looking for a cheap accommodation the Lake Side next to the only lake of Phnom Penh will be the place to pop in. There is plenty of very basic budget and mid-range guesthouses from US$1.5-10 per room and night. The sunsets from one of the wooden platforms over the Boeng Kak Lake are pretty famous in town.
