We were four friends traveling together. In the start we had two separate rooms. The girls in the other rooms complained about a strange smell in their room. We all upgraded to a bigger room with two big beds and separate washrooms. The staff was friendly, though a shame that the rooftop terrace was not used since it featured a bar and a jacuzzi.
I spent 5 nights at the Bougainvillier Hotel in Phnom Penh in August 2014 and had a great time. The staff are wonderful. I had pre-paid my stay. When Air Asia cancelled my connecting flight, I was stuck in Kuala Lumpur for a day and arrived a day late in Phnom Penh. The lady behind reception felt bad about this and upgraded me to a terrific river-view room.
If I ever come back to Phnom Penh I would definitely stay at the Bougainvillier in a river-view room again. The room was absolutely massive, great balcony, great bed, new TV, terrific bathroom.
The staff were also terrific. Breakfast is until 10.00. When I slept in and came down at 10.15 one day, they kindly put some food back, offered to fry me some eggs - awesome!
Lovely hotel with excellent owners! Good, quiet location with clean rooms cleaned daily. 10 minute walk to the river however a great selection of restaurants within 200m. Lovely pool to relax in also. Would definitely recommend!
