We didnt' go to the apartment on the photos, it was an other one on rua 31 de Janeiro and it was amazing! It was big, newly renovated, decorated with good taste, had everything you needed and some more, perfecly situated, in summary: great! We didn't meet Joao but Luciana was there to welcome us and gave us some great tips on Porto, by the way thanks Luciana (the porto sangria at Taberninha Do Manel was indeed amazing).
