Location is good for people who want to enjoy the nightlife of Porto because there are a lot of clubs and bars around. At night its noisy when you sleep with open windows.
It is also good located for exploring the city center.
The bed is comfortable and the room is bright and big.
The bathroom is very very old, dark and a bit unclean. The worst part was the smell (sink?)...
That is the reason why the price-performance ratio is not the best.
