We could not have asked for a better experience in Porto. Mario is a fantastic communicator and went above and beyond to make sure we were well informed even before arriving at his BnB. We used his app (Mario's Porto Route) many times. It is awesome!! The place is beautiful, clean, open and comfortable. We loved how close it was to Livraria Lello, so many restaurants, and beautiful old buildings. Our only regret is we didn't allow enough time to enjoy Porto more!
