Joao and Andreia are very friendly and did a great job furnishing and decorating the apartment. They gave me great local restaurant recommendations. The apartment was a bit on the outskirts of center but we had a lot of space as the apartment is very large- about a 15 min walk to the "center" but there is a street with a lot of cafes and restaurants about 5 mins away. It's an easy, enjoyable walk to the center. Great experience in Porto.
