Luis's apartment is an amazingly central spot for getting around in Porto, you can enjoy the beautiful views from the living room windows over the river. The Apartment has lots of space and it's lovely and clean.
There are so many things to do in Porto but if you have time do explore the neighborhood. It's very close to the Porto Cathedral and to the shopping street. Once you were at the Cathedral hop on down to the train station which is only a couple blocks you cannot miss it.
Louis was great at communicating and anything you need you can always ask him.
The building is great as it has parking underground and an elevator.
