Perfect location to explore Porto! Everything is within walking distance, many bars are right in front of the apartment.
Moreover, the host was really helpful and gave us a great introduction on the places to visit in Porto as well as recommendations for the best places to eat.
Pick-up and drop-off at the airport worked very well.
As it's in the heart of Porto's nightlife area, it might be a bit louder on the street at night. However, with closed windows (AC is available in the room), it was fine.
