Gisela's place is wonderful and newly renovated so everything is very clean. Although I didn't meet Gi myself, she was very friendly and helpful in our messages. Her lovely cousin Joana met me at the place and was really kind and helpful. The room itself had almost everything I needed for my stay with lots of additional treats such as sample of local wine! The area is right next to the river front of Vila Nova de Gaia and all the sights but is in a quiet side street so you get the convenience of a quiet nights sleep and easy access to beautiful views. I had no issues and would thoroughly recommend :)
