Joana's place is absolutely fantastic. We would definitely stay there again. It is very centrally located and we were able to walk to all of the sights we wanted to see (we walked to Gaia, the waterfront, Palacio da Bolsa, Crystal Palace gardens, Livraria Lello, Torre dos Clérigos, etc). Joana had fantastic recommendations for restaurants and places to go, as well. There were a number of restaurants within five minutes walking from her place. Public transportation seemed to pass regularly, but we opted for walking. Her apartment is on the top floor (3 flights), and was an excellent way to work off all of the pastel de natas and pastries we ate every day! Thank you, Joana!
