This resonates with me. I enjoy being at my grandparents’ home. And it’s exactly as you mentioned, if I would describe all the stuff in the living room it’d be called “cluttered”. Yet it feels “homey” and I feel pretty relaxed whenever I sit there to read a book.

And then on my side, for the past 15 years I moved to a new place about every 2-3 years. Never really invested in making it feel “homey” because I’m not sure how much space I’d have in the next place I move to.
