I stayed this hostels for 2days.
What's superb of this hostels is to organize the own activities such as, hiking to the sign ,BBQ on the garden and preparing for the shuttle bus bound for the beach.
If you wanna join, all you have to do is just to fill out the form at the front desk.
Mostly participation fee is too reasonable.
But in terms of comfort, I didn't get accustomed to live with several people though this was not fault of the hostels, it was my fault.
