Great place. Small but didn't feel small. Everything you'd need as a couple or solo traveller. No negative surprises, everything well represented in the photos, comes equipped with all the modern indemnities and is very well laid out to get most out of limited space. Many cafes, bars and restaurants in the area, although you'll probably prefer to walk some 5-10 minutes into the more touristy/lively areas of town around either side of the Duoro river or further inland towards the central plaza/main shopping street etc. But altogether not at all a bad location from which to be exploring Porto. Only minor drawback was that the key pick-up/check-in is done at a place that is not particularly close to the flat itself.
