I live in a new build terrace, neighbours on both sides are extremely considerate. I'd like to get a piano (but an upright not a keyboard) for DC and me to learn on. You can't hear a peep from any house if the doors are closed but any window or door open you can hear everything. I'll obviously never play with doors or windows open. Would you be annoyed if you were them? I could play some piano music to test that they wouldn't be disturbed. If I ask them outright they'll say it's no problem.
