Mario's appartment is located in a great area with lots of character, lots of restaurants, cafes and boutiques. The appartment itself is a spacious studio, bright and welcoming, on the 3rd floor - no elevator, beware of too much/heavy luggage - of an ancient but very well maintained building. We learned the hard way that downton Porto isn't car friendly; parking can be an issue, but Mario pointed us to a very convenient and well attended parking lot around the block. The street below can be animated at night, and you might be awaken early by a seagull concert, but it's all part of the charm of the experience. Communication with Mario, in advance and the day of, and access to the appartment were a breeze. A lovely stay.
