Our little apartment building isn't always the quietest place. Especially as I type this. But I really can't complain. You see, the guy who's causing the "racket" is a really amazing pianist. He just started up with one of the "Well-tempered Clavier" Bach pieces and is now playing all sorts of other stuff. It's all quite pleasant.
When we moved in, and I met him, I commented on the piano and asked if he could play it a bit louder as we really enjoyed listening to the music.
