Aida's place worked out really well for us. It's a short walk to the nearest subway station and a quick 15 minute trip to the city center. We loved the location, which gave us a more local view of Porto and allowed us to easily park our rental cars after some day trips to the Duoro Valley and Parque Nacional Peneda-Gerês.
Aida was really communicative and helpful when we checked in. The apartment was really big and gave our group of 6 people enough room to hang out together and get some privacy too.
