We downsized when DH retired by selling the house & keeping some ground with a 3 car garage on it.Eventually it was made into our retirement home.Large living room & family room, one bedrm & bath....plus a utility room used for my sewing space.We also have a lovely front porch where we spend lots of time from Spring till Fall.
When I had knee replacement surgery we were so glad to be in a one level house.This yr,I had a hip replaced,so smaller is better....for us.I can clean the whole place in a few hrs & deep clean in a couple days.
It also means lower utility bills.We're just 3 miles from town on a level road.It was a good decision,but one that is different for everyone.
