Location: Perfect, across the street from the river and just a block away from the palace/silver pagoda. Walking distance to Wat Penh.
Rooms: Very, very loud. We were in the back and could hear everything in the hallway, the blasting TV next door as well as what sounded like a dog fight for a couple hours during the night - and that was with ear plugs in. The room itself is nice looking, but everything appears like it was put in by an amateur.
Breakfast: Decent, variety of options.
Rooftop: Nice and underrated in other reviews! The pool is very lovely, if a little cold in January, and the view is perfect overlooking the river. The bar was in fact open (starting @ 5 pm) and the staff helpful. We had the top to ourselves both Tuesday night and Wednesday afternoon when we were looking to escape the heat. There was no scum to be found and it was perfectly clean.
Staff: Helpful with arranging airport pickup/tuk tuks, if not a little pushy for booking tours through them (killing field anyone?). They would not give us restaurant recommendations, telling us that we could make our own choice, which I found to be odd as we had just arrived to the city. Our taxi driver from the airport said the same thing and told us he did not like the city, again which seemed odd.
Food: Decent western food and drinks. Drinks are reasonably priced while food is not. You get a minor discount upon checking in which helps.
