I think what makes a home beautiful is the kinds of people living in the home, how clean the home is, and the home's personality (as in the artwork, how its structured, how the furniture is arrange, etc).
When it comes to the types of people, I have to get a good vibe from each person. There are certain people who I just don't get good vibes or feelings from and that kind of ruins the atmosphere of any place, not just a home.
I don't have a certain style when it comes to the home's personality. I tend to like a minimalist approach with tons of open space, a very artsy type with a lot of decorations, and a a tight-fit style where all the furniture and decorations are tightly packed together perfectly like a puzzle.
