Pedro was an excellent host - very accommodating and willing to help/be available at a moments notice. He took the time to explain how everything worked in the apartment with a little tour. The place was very clean and was exactly as advertised in the photos. We were 3 people and it was the perfect size, as there is a separate room with ensuite bathroom in the lower level, and the upper mezzanine had a single bed that had another single pullout underneath. The couch transforms into a bed, but we didn't have a chance/reason to try it out.
The location of the apartment was perfect, as it was 1 block away from a metro station, with plenty of cafes and even a mall with a gym within walking distance. Even from the famous Baixa district, it was a short cab ride away for nights when we were out having drinks and discovering the great city of Porto. Will definitely be using Pedro's apartment again next time we visit!
