Truly fabulous location and view, as shown in the listing. Great little balcony for boat- and people-watching, and the lights of the port-wine lodges on the opposite bank in Gaia. Helder was very responsive, obliging and patient. He met us outside the building, showed us where to park, sold us coupons for the carpark which reduced the parking fees substantially. Apartment is well supplied with everything you'd expect in a service apartment (though the washing machine is actually a dish-washer). It's just steps from plenty of restaurants (2 excellent ones are Adega S Nicolau and Ode) and shops. Also very near several major sights and tram line to Foz do Douro. If driving, be aware that the apartment building is in a narrow cobblestone lane with a slope; nearest carpark is up the slope and across a road - took us about 10 minutes dragging suitcases over cobblestones to get from carpark to building. Minor gripes: only 2 hangers provided, shower cubicle door faulty, can get noisy at night as it's in a very lively touristy area but that's the trade-off for the unbeatable site.
