Picture perfect!
This apartment has just the view shown and is in an ideal location close to Clerigos Tower and the Cordoaria / Clerigos bus/tram stop.
I was visiting Porto to be a tourist and also telecommute, and my stay was just great--when I wanted to go out and sightsee, all of the buses trams were right at the doorstep, and when I needed to work, I had that beautiful view and good wifi.
Maria and Ana clearly work hard (and use excellent taste) to set up the apartment, and it shows. The apartment is extremely clean and well-stocked, and it's only two flights of stairs up (2nd floor in European terms, 3rd floor in American terms).
One tip: if you come from the airport, I strongly recommend the 601 bus over the metro. It is direct (no changes) and the line terminates at Cordoaria, so there's no worry about missing the stop. The walk is then extremely short and the only hilly part slopes down.
