Not sure if Francisco owns the place or works for a bigger company, but he was so vital to our trip. He was very flexible when our plane from Barcelona was late and gave us incredible recommendations for places to eat (my wife and I are BIG food fans, especially Portuguese food). His advice was a big part of what made us extend our stay in Porto.
The apartment was great, too (unfortunately it was already booked over the weekend, so we had stay at a different Airbnb when we extended our stay). It was very clean and comfy and a perfect temperature with the windows open. Of course, the balcony was the best part - we couldn't get enough of the view of the rooftops and even a little peek of the river. A perfect spot to eat treats from the bakery around the corner. We had a very memorable stay.
