Gisela was great! Super friendly and told me all I needed to know about the area. The apartment was perfect. I only stayed 1 night, because I was moving to a larger place with another friend but actually wished I had stayed at her place the whole time. Very centrally located but block wasn't too loud. Close to sites, shopping, restaurants, and public transportation. Very nice balcony to relax with a glass of wine. Small kitchen had everything I needed. Apartment was very clean and simply but nicely decorated. If I return to Porto, I will definitely go back to her apartment.
