This is a wonderful home base for your stay in Madrid. It's centrally located with convenient metro stops, easy rideshare pickups, and a wonderful terrace to hang out. (The terrace does mean it's a 5 floor walk up-- worth it.) It's on a quiet side street so traffic noise is minimal. The only thing we heard at night was the sound of nearby restaurant patrons, and it wasn't intrusive. I would highly recommend this apt.
