This apartment is located in downtown Madrid and you'd have access to metro and bus. However, you don't really need to use public transit as you can walk to most of the historical locations and attractions of the city within 20 to 40 minutes.
The biggest issue is the noise which could easily be heard from the street and other apartments until midnight. Next is the elevator which could be accessed through a few steps from the main entrance and to the apartment.
There's a washer in the apartment that we used once and it was convenient. Also used some of the cooking facilities.
