Although I only stayed in Cabinas Back Packer for one night, it was a great experience. The hostel is located right on the fringe of downtown PJ, a minute walk to main street but just far enough away to escape the noise. Frederico, the landlord is a lovely man with a warm and welcoming heart. The place is very clean, with a great kitchen and common area and very comfy hammocks. Frederico will even do your laundry for a small price - afterwards my clothes were cleaner than they've ever been. If you're stopping through PJ, this place will provide a really great home base for all the amazing surroundings!
