Joao was a great host. We arrived in Porto late (after midnight) but Joao still met us at the apartment and gave us lots of tips for our stay and a couple of very useful maps. The apartment is well-equipped and very well located for access to the riverside and old parts of the city as well as wider sightseeing. Joao recommended lots of excellent restaurants in the area and was very knowledgeable about Porto generally. We had a great stay. Thanks Joao!
