I've ruled out stacked condos (since I wouldn't want to be on the bottom and I doubt people would want us on top) - except for a well-sound-insulated new building.
Does someone play a musical instrument/music or?

Life is not perfect in a condo but I would not be interested in the upkeep for a standalone or even semi-detached home. A sister lives by herself in a 2 bedroom semi detached--2 levels. Her home. She has balance issues at times, and now is deaf in 1 ear. She ...is only 54 yrs.
