Bruno's apartment is absolutely stunning, specially the views from the balcony. It's a walking distance away from both the bottom and the top of the Luis I bridge, so you can reach Porto in a few minutes.
Bruno is the best host I have ever had on Airbnb. He told us all the places we should visit in our stay in Porto as well as the best restaurants to eat the typical dishes. We went by car and he helped us park, reserving a spot for us before our arrival.
I would definitely recommend Bruno's apartment for anyone wishing to spend a relaxing time in Porto having breakfast with the best views.
