We really liked the Mondulkiri Boutique Hotel. It is a charming little hotel with very friendly, helpful staff. The room was spacious and comfortable and everything worked fine. The a/c was run by remote control and also an unmarked wall switch, part of a bank of three that also controlled a light and fan in the bathroom, so that was a bit tricky to get the hang of. Included breakfast was passable, not much selection and pretty basic, but fine, and the staff there made us feel very welcome and comfortable. The front desk staff arranged a tour for us. They have their own tuk tuk driver who took us to the Killing Fields, the Tuol Sleng Prison museum and the Russian Market for a very reasonable rate, which included his waiting for us at each stop for as long as we wanted. We took considerable time at both the Killing Fields and the market, where we went to a restaurant for a meal but the driver didn't complain or seem at all put out, and seemed very pleased with the modest tip I gave him. The staff also arranged our bus trip from Phnom Penh to Sihanoukville, which was trickier than normal because it was the start of Cambodian New Year, and several buses were sold out. The woman at the desk called around and finally found us seats on a bus. We felt really well taken care of while staying at the Mondulkiri, and will always remember it fondly. The immediate neighborhood is a bit rough, but that could be said for most of the city.
