Great location, you practically don't need to get any means of transport to go anywhere in Porto! Nice studio, with all you may need in there :) Mario was always available in case something happened, or to just give a few tips on where to go. He also left us a nice map, thought by himself, with lots of advices on what to see/try. The breakfast was also good! A nice discovery on airbnb. One tip: the heating was a little bit poor, but as an Italian I know buildings don't always have heating in continental Europe, so thank you for the effort (blankets and heater did the trick)!
