This place was everything the positive ratings promised and more. Unbeatable location. (Though an address for taxi/uber would help to not get stuck unable to access some of the tiny pedestrian only roads- our uber left us a few blocks away and we didn't know any better about how to tell him where to get us. Using the intersection of the nearest car accessible streets worked where google maps could not find this address for some reason.)
The view is priceless. The place was beautiful modern lines and clean. Lovely bathroom and kitchen (even though we didn't cook). A definite not-to-miss if visiting Porto.
