For me it was a perfect location. I arrived by plane to Porto, took a uber for 16€ that brought me directly in front of the hostel. I stood one night and went on by train. The station is a nice 5 min. walk away and you can find a cafe for breakfast on the way. So for me it was a perfect stay. If you intend to stay longterm in Porto, you might miss some comfort, like a chair and a table in the room, but just for sleeping morning toilet, perfect.
