Eduardo's place was excellent in terms of location. right next to all the main attractions of Porto and very easily walkable. it was very comfortable, barring a couple of things - the kitchen could do with a kitchen towel, and we also faced a power issue in the middle of the night (it seemed to be just our unit in the entire building which was affected). Eduardo didn't respond to us until later that day though once he saw it he was immediately helpful and fixed it. great place and I recommend it to anyone visiting Porto!
