If this is available, book it! Luis was a wonderful host- great communication, flexible, and even met us at the train station on arrival. He is very kind and knowledgeable about his town. The flat itself is a typical European apartment with a bedroom and then the kitchen and bath across the hall. Not a bid deal since you're on the top floor so it's private anyway. The real headline is the balconies! One on each side of the flat but the one facing the river is stunning. We wanted to do some port tastings and we were a short walk across the river. Tons of bars/restaurants downstairs but still quiet at night with the balcony door closed. Don't hesitate!
