Samsara villa is a lovely boutique hotel with tranquil pool and gardens. Probably the calmest spot in Phnom Penh. It is hard to find though..make sure you have the mobile phone number for tuk tuk or taxi drivers to be guided in. Phnom Penh isnt somewhere that is easy to walk around so you do need to take tuk tuks.
We were upgraded and had large stylish suites. The hotel hadnt opened long so there were still some bits and peices to sort out. Service was relaxed giving a warm and casual atmosphere.
