We have just returned from a five day stay at Jorge's place and were extremely happy. There was lots of space for us (a family of 4) and the location from the airport was excellent, being only a short (if uphill) walk from the Trinidade metro station which is the central stop on the airport line. The apartment is an easy walk to the historic centre and shopping areas and very handily has a pretty good Pingo Doce Supermarket about 5 doors away around the corner! There are lots of restaurants within an easy 10 mins walk too. Communication with Jorge was excellent at all times and he was waiting for us on arrival to the apartment for check in without problems. We will definitely stay again on any return trip to Porto.
