Most people come by boats. Any boat coming from all towns except Santiago will drop you off at the main dock. From here, walk up the path and take the first right. The hostel will be about 2-3 minutes down this road. There's a light up sign in front, its a large 4 story white building with two restaurants in front, Forbidden Fruit and Pita Sabib. All shuttles will drop you off in a very similar spot and follow the directions above.
