Nelson's apartment is located on a quiet street just a few minutes from the nearest metro station, as well as a large grocery store. Many tourism spots are located within a 15 minute walking distance, and we barely used public transport at all during our stay in Porto. We were welcomed by Nelson's father, who was kind enough to show us how to get to various destinations, gave us some transport tips (there is a cheaper public alternative to hop-on, hop-off buses), and was happy to answer our questions. We also spent some time on the two balconies that this apartment has. We had a great time in Porto, and should we return in the future, we would be happy to return to Nelson's apartment.
