Good and bad comments here but my experience has fallen on the bad side of them.
Staying on the 3rd floor I went down for a coffee one morning and when I returned my ipod and $1000 had "gone" missing. Taking this up with management the reply that I heard was "they are all family, you accuse them you insult me"
Well this sort of ruined my holiday and would not recommend this place to anyone at all.
So if you do go to Phnom Penh avoid this place like the plague.
