The apartment is in an amazing location, the holiday could be perfect only by staying on the balcony and looking to the Douro and the bridge! The building is old and someway "particular" and you won't have all the comforts of an hotel, but that's the Airbnb experience and we loved it!! Luis is one of the best host we've met: he is super friendly and helped us before and during the trip.
Highly suggested!
