I stayed at Paulo's apartment for a whole month with my wife, and cannot recommend it more. The apartment itself was really comfortable and spacious and had everything we need, plus being extremely well located and close to lots of major places to visit in Porto (plus supermarkets, restaurants, bars, subway, etc) . As a bonus, the terrace was a great and private place to relax outside and appreciate the view. On top of all that, Paulo was such a great host, who took time to talk to us about Porto, point us to a number of things to do around town, plus being super quick to respond at whatever question we had. We're really thankful and will for sure want to stay there again whenever we come back to Porto!
