One of the best AirBNB experiences I've had. Marco was an exceptionally gracious host. Our flights were delayed, causing some difficulty getting into Porto, but Marco was very accommodating with check-in. During check-in they were happy to offer suggestions of where to eat and visit.
The AirBNB is in a great location: great food is just a step out the door, many of the tourist hot-spots are a short walk away. While being close, it's also a very calm and quiet AirBNB. The balcony overlooks a courtyard, offering a break from the hustle and bustle of the city streets.
