We had a wonderful 3 days at Cláudia's en Mafalda's apartment. The view on the Douro and the Bridge is phenomenal. OK, you need to do some exercising along the stairs but that comes with the charme. The apartment itself was spacious and very clean.
Cláudia and Mafalda even picked us up at the metro station nearby and walked us to the apartment. They were great and helped us with touristic things and even booked a taxi for us to get to the airport very early.
So thanks! A super experience, we will come back some day ....
