The apartment is in central location. Walkable to Porto point of interests and metro stations. It's also very close, one station away, from the main train station - Porto Campanha. The downside would be bit noisy coming from the street and bit an issue if you are a light sleeper. Pedro himself is very relax with the check in and out time as I initially intended to keep my luggage there and he let me stay as long as I needed. Thanks Pedro!
