Constantino's place was great- spacious, lots of natural lighting, a really comfortable bed. It is a little bit of a hike if you want to walk to central Porto, but there is ample public transportation nearby. It's located at a busy intersection, but you can't hear anything if you close the windows and the shutters. My only complaint is that there were moments when the wifi was unstable while I was on Zoom calls for work. They were brief, but very inconvenient. Constantino is a delight, kind, and extremely communicative. I would definitely stay here again!
