I stayed in this hostel not as a customer, rather as a friend of the hostel owner, Hero, whom I met online on a couchsharing site.
He's really friendly and helps his guests selflessly. The hostel is not so centrally located though there is a direct ferry/bus service available to the Khaosan Road, which is the tourist part of the town. You can also meet many like minded backpackers in this place as it is always buzzing with travellers from around the world.
