The location. It was perfect! Everything is so close, you could walk around the city for hours and still be just a 15min walk to the apartment. The host was super nice, allowed us to check-in after midnight because of our flight, provided insight into places to go and and things to see in Porto and tips on how to get around the city and to/from the airport. We had a lovely weekend, saw the prettiest sunset and had the best cocktails (Porto Passion!) ever.
