One of the best air bnb' s we stayed at. Actually better then some Hotels :) we arrived past midnight but Nuno waited on us. Everything you need is near by and all the atractions in walking distance. We only used the public transport (wich is pretty good and cheap) to travel from and to the airport and for a daytrip to Alveiro and the atlantic coast. A highly recommended Trip for someone who stays a bit longer then just 2 days in Porto.
Our favourite two restaurants we would like to share are "Casa da Breganza" (very typical and simple food with many locals) and "Droop" for a lovely evening with good Service, wine and super delicious Tapas.
