The apartment is super-elegant, clean and furnished with good taste. Doors to the balcony are new and isolate well. This is the only floor with a balcony and it is really a luxury to sit there and watch the bypassers on the street below or listening to folk singers in the street.
However, if you are a light sleeper I would recommend to bring some earplugs - with those there is not a problem to get sleep even during weekends. The street itself is very cosy with lots of smaller cafees and shops.
Pedro was awaiting us as promised an was helpful in explaining about the various things to see and do in Porto - which we did. This is a very nice and now, tidy city where most things can be reached by foot.
