Seaview Rainbow is North-west part of Koh Phangnan in Ao Srithanu, completely away from the partying and crowds at Thongsala - which may or may not be what you're looking for. A songthaew ride away from the ferry port of around 20 minutes, also further to the North is the bottle beach which is worth the trek. Seaview Rainbow is basically a collection of beach huts set out in a semi circle facing towards the sea. We were welcomed by Gao (sorry bad spelling) the owner who was very laid back and after showing us to our hut, told us to relax and enjoy his swimming pool (the sea) with a cheeky smile. Rooms are spacious with Thai style bathroom/shower, veranda and hammock attached. This family run place is so friendly and homely, it's like your own slice of paradise. Couple restaurants, pharmacy and ATM nearby. Enjoy!
