First and foremost, Joana is a great host! Our flight was delayed by several hours and she made herself available late at night for our check-in and took the time to give us great pointers about Porto. The apartment is "just outside" the main action (less than a 5 minutes walk), which makes it quiet and perfect to sleep at night. Everything's at walking distance; attractions, shops, restaurants, wine cave/cellars, etc. Strongly recommend this place!!
