Ana and Joao's apartment is absolutely perfect. I've already recommended it to a friend visiting Porto in a couple of months. The location makes it easy to visit various parts of the city. The apartment itself is beautiful and very well decorated with a lovely blend of modern and traditional. If I were a single person in Porto, I would love for this studio to be my home! Lovely hot shower, full kitchen, and a cozy breakfast and lounge space. My arrival time kept changing slightly and Joao was able to accommodate me. He gave me great tips about where to go in the city and there was a welcome tipple of port.
There is only one small negative to the building, not the apartment itself which is basically perfect, but rather the hallway area. As noted in the description, there are cats that roam the hallways (four). They wont bother you if you dont want them to or try to get in the apartment, but the hallway has the distinct smell of a house that has a lot of cats, so perhaps not the best place for someone with an extreme cat allergy or someone very sensitive to smell. This is just the hallway, the apartment itself has no odor.
