Rafaela's place was amazing. My friends and I stayed there over the weekend recently and it was a great base for our Porto trip. It was conveniently located to tourist sights, including the popular Livraria Lello. We were able to walk everywhere conveniently and didn't need to take public transport.
Rafaela was a great host. She responded quickly to our messages and allowed us to leave our bags for a while after we checked out.
Would definitely recommend friends and family to stay here if they visit Porto.
