As far as Porto goes, to be any more central than this place, you'd have to sleep in the train station! The building is a little rustic, but host Vitor keeps it clean, and Vitor himself is a real character - so friendly and funny and helpful. He was born two streets away and has been running this place for 17 years, and he loves doing it. Listen to his tips and be nice to him! My room was surprisingly quiet, considering the place's amazing location, but that speaks to Porto in general. And I loved having my own attached bathroom (complete with toilet, sink, bidet and shower). Pensao Douro is an incredible deal.
