We had a great time in Porto (better than Lisbon, we thought)! The apartment is about 35-40 mins away from center. Locals are very nice and accommodating. Pedro checked us in and was super helpful and hospitable! He took about 15 mins (or more!) of his time to go over the city map with us and gave us awesome recommendations to restaurants and best spots to watch the sunset. The only thing we were iffy about was the flooring in our apt (room 6) — very squeaky and loud, otherwise, everything was great.
