I can only speak for my sister, who lives alone. She sold her home and bought a condo. She loves it. No shoveling, yard work or other outside maintenance etc. Her condo association does all that. She also doesn't have hobbies so she has plenty of room.
Downside is she loves to plant flowers and the rules are very strict.
I guess it really depends on your lifestyle and what is/is not important to you.
Wouldn't work for my husband and me but it's pretty much perfect for her.
