Cláudia's place is fantastic. Right in the heart of Porto but on a very quiet street. We walked everywhere we wanted to go in town. The apartment is very modern, great bathroom and kitchen, comfortable bed, great views, and very comfortable to hang out in. Cláudia provided us with a bunch of restaurant recommendations and maps of the city. She quickly responded to any questions I had and went out of her way to be a great host. You should book this place, I know I will stay here again when I come back to Porto.
