Nice apartment with full kitchen, clean and spacious, and a good sized balcony with lovely views.
The air-conditioning was sometimes a bit slow to start, but otherwise it worked very well.
The Cathedral Sé is just opposite, and the Sao Bento train and metro stations are only a few minutes stroll away. Most sights are within walking distance.
Our flight arrived very late. We asked for transportation from the airport (that also included late check in), and everything worked promptly!
The elevator broke on the second day of our week-long stay, so we had to walk the stairs to the 5th floor. But that's of course not related to the apartment itself.
