Paulo's Airbnb was lovely! The place was clean, comfortable and the location was PERFECTION to explore the city. Plenty of restaurants and bars close by which we loved. Supermarkets were a bit far but it was not a big issue. The self check-in went extremely smooth and the fact that you use a code to get into the building and into the flat is wonderful as I am always afraid to lose keys. hehe. I really recommend Paulo's bnb if you are going to Porto. Thanks for everything, Paulo!
