I've never thought of this for such a long time.
My happy place would be in a cosy little house in a lush green area, lots of trees and open ground with a stream near by would be nice. Maybe a few dogs to keep us company. Far from the city, with my nearest neighbour about 4km away. A cup of hot tea in my hand, cuddled close to my partner on the swing in my porch looking out at our future child with our fur babies running around playing. The sound of giggles, the scenic view, the body warmth from my partner and the sun, I crave it. The feeling of no worries, nothing to rush to, to stress about. just to sit and enjoy the moment.
