The best hostel I've ever stayed! I've already tried many hostels around the world and also in Oporto, this is the best one by far: sleeping space with privacy (curtains), individual locker/light/outlet, free breakfast, free towel, perfect location next to Santa Catarina street and a large garden with a bar to relax after all day walking arround.
I recommend this place to anyone! It looks like a boutique hostel, tidy and clean. No loud parties, just a friendly, relaxed and social atmosphere. Location is perfect, right in the middle of the city centre and next to direct metro to the airport.
