My friend and me stayed at that hostel for about 10 days. The hostel is nice and clean. There is a outside kitchen so you can cook your own meel if you want to.
Close by is Ahangama {5 minutes by bus 15 rupee} You can buy food and fruits there.
When you want to surf you also can take the bus (15 minutes 30 rupee) and go to weligama Island. Do never ever take a tuktuk. They are just incredible expensive.
The hostel itself we can recomand. We also recomand to eat at the restaurant which share with the hostel the same area. It is called gully.
