Diogo's place is clean, comfortable and in a great location. We were greeted by Jose (who is super nice!) and he had a bottle of port and pastel de nata as a welcoming gift for us. Great communication as well. We had a small problem with the stove but Diogo/Jose got back to us within a few minutes and with his help we were cooking in no time! If you're ever visiting Porto I would definitely recommend staying here.
