One of the best Hostels I have every stayed at and I have been through 24 or more countries by now. It clean, hip, modern, up to date, organised, awesome staffing, with well planned activities for city tours, wine tasting, bar hopping and so on. They offer dinner with drinks for 10 euros. A electronic wrist band is given to you when you check in and it gives you access to the building, your room, and unlocks the lockers underneath your bed. I happened to stay in the 4th floor and the lack of elevator gets tiring but no where near as tiring as walking the streets of Porto itself...its so steep out there!
This is one of those hostels you need to book in advance as it is almost always fully booked. read more
