Joana is a lovely sweet young lady.
She tried to help me my stay to be a very comfortable one in many ways from the early time bag checking, map and very local tips, and whenever I needed her, she was there within minutes.
Her apartment is bright, clean and well equipped lovely one as like her.
Heaters worked nicely, so could stay warm inside when it rained chilly outside.
It's located in centre of historic porto, and I could learn very next building of hers has been used for many old era intelligents gathering place, the cafe as well from the local book.
Anyway... I for sure recommend her apartment.
