Can’t recommend enough Helena’s place. It’s such in a good location close to a lot of places of interest and great restaurants. Also Helena is a maevelous host. Our flight arrived early in the morning and she was so accomodating she agreed to do an early check-in and greeted us with some delicious traditional pasteis de nata. She also explained to us very well the city and gave us tips of where to go. Will definitely stay back at her place if we ever go back to Porto.
