Great relaxed vibe at Thongtapan - the stilt bungalows are basic but stylish and the staff are very helpful. The manager (Mint) is fluent in English and very helpful and friendly. Restaurant is pretty good but the stand out feature is the beach bar with cocktails worthy of any decent Bangkok bar. I would recommend it as the best place to stay on Thong Nai Pan. Try out Luna, Jip and Handsome Sandwiches while you're there. Thong Nai Pan is a little more upmarket than most places on Ko Pha Ngan but very suitable for couples who want to get a rustic island atmosphere.
