We had such a great experience staying at Mário's apartment. The location was fantastic- it was quick and easy to walk anywhere in the city. We appreciated the minimalist decor style, because it felt so clean. We utilized the kitchen to make our own meals, and all necessary pots/pans/utensils were there. The bathroom didn't quite match the standard of quality as the other rooms, but it was fine. We were able to park our rental car in a nearby shopping mall (for only 8 euros/24 hours- a steal of a price for downtown Porto parking!) Mário was quick to respond to our messages and helpful.
