Although it's a bit tricky to find, the location is relatively close to Porto's central district. The hostel has a naturalistic style. I especially like the "fat boy" sleep bags in the common area. There are nice facilities, including a common kitchen, computer area, reading lounges and a cool sky terrace. The staff is among the coolest staffs I have ever met :) They gave very down-to-earth advice. I especially like the tour opportunities the hostel offers: pub crawls (it's amazing, most leaders really know how to dance!), free walking tours, paid wine tour and such. The hostel offers a very yummy breakfast, too (it has the most variety than all the other hostels I have stayed at so far).
