Jaya's is a massive hostel in Haad Rin with private rooms & dorms, spanning its own little block, a couple minutes walk away from the beach. I have stayed here for two full moon parties and it's just a great party hostel, very social and lively, with a fantastic friendly staff! They all remembered me when I came back for the second time a couple months later! The dorms are a good value & have functional aircon. The beds are quite hard - oh well -people are usually too passed out to care about that!! There's a big bar/restaurant/social area where you can chill & meet people and there are street parties every night around full moon! Highly recommended overall!
