Truly a marvelous location and beautiful apartment. The view from the bedroom with twin beds is breathtaking.
Our only issues with the place were that the living room was much smaller than we expected, and the amenities / utilities were poor. The beds were a bit stiff. The couch and living room were too small to enjoy and the tv was quite small. Additionally, the bathroom towel hangars were really poor and broke when hanging the towels... Finally, the two bathrooms have a limited hot water supply so you should shower quickly.
At the end of the day, the condo is great for it's location and view. Only 15 minutes by foot to the city center, and right next to the river. Really loved the place and loved Porto.
