Really enjoyed our 3 night stay at Guest House Douro! Amazing location, our room looked out on the river and Gaia but was still very quiet thanks to double paned windows. Staff were so friendly and helpful, made dinner reservations for us. Breakfast included a mountain of delicious tropical fruit, such a treat! Also yogurt, cheese, eggs, toast, granola and fantastic coffee. Just be aware that rooms are quite small—but cleverly designed to make the most of every inch. Highly recommend!
