Fabulous location, very close to loads of restaurants and shops, plus easy access to/from the airport. You can just walk to the city center and most of the interesting places.
Clean and quiet too (mine was facing the backyard but I don't think the street is any noisy either.
Jose was very easy to communicate with and prompt to help me with my luggage (my flight was in late the afternoon) so I give him an extra plus for this.
If I visit Porto in the future, Jose's place will definitely be my first choice.
