For Accomodation options in Khanom or Koh Phangan just contact me and I do my best to help! ;)
In Khanom my favourite Accommodation is @ WhiteBeach Service/Nai Phlao Beach. This Family run place is just amazing, so friendly, good price and fantastic thaifood.
When it comes to renting Houses per month or longterm in Khanom I can recomend Yadaview @ Nadan Beach. Their houses has everything you need and is well-maintained and the owner is very friendly.
