Is it smart?

I recently moved into a new place and have met some of my neighbors and they seem nice and their like “yes my name is such and such and I live in unit such and such” and I don’t feel comfortable letting them know my unit as i barely met them. I am very cautious when it comes to giving me personal things like even though we live in same apartment complex and I am like yes I live on the other side. I guess living alone as a relatively young female makes me more alert an anxious to reveal exactly where I live
