We arrived later than planned because Porto's public transport system is something else.… (Each needs their own card which you top up with zones depending on where you are going and then the ticket is valid for an hour?) Anyway, Isabel's father waited for us and was very nice. The place itself is as lovely as the photos suggest. Though it is rather noisy (busy street out front and construction work downstairs) for us the heavenly shower made up for it. We explored Porto mostly by foot and Isabel's place was well situated for that. We never actually met her but she did write to see if we needed anything. I do recommend this place.
