If you plan to visit Oporto, Mario's apartment it's a great choice. It is well located, close to the center- shopping area. Mario is a fantastic host who facilitate us a map of the area with good recommendations on restaurants and places to visit. He was kind enough to let us rent his parking place (with a very cheap price and close to the apartment). The rooms were wide and decorated with good taste. Also the beds were big and comfortable. The terrace is really nice, we felt like home.
