Mario's place is in a great location! It's right across from the metro and there are lots of shops and restaurants in walking distance. Since it's downtown you can walk to many of Porto's major attractions. The room was spacious and clean, and Mario was very helpful when we needed directions and an extra electric converter. The building also has an elevator, which was great when we came in with our luggage! We had a great time and hopefully we'll be back some day!
