Things you notice when visiting other people's homes........

I was reading this article "The seven surprising things house guests notice when they visit your home (and why they DO judge you if it's messy) " which was featured on Daily Mail Uk.

1. Cleanliness and Mess
2. Bright Walls
3. Pleasant Smell
4. House Plants
5. Art and Books
6. Furniture Placement
7. Light Sources

To be honest they are not really a surprise.  

I always notice if people's houses are a mess.  Bathrooms are a pet peeve, as I like to use a clean bathroom.....

A bright wall always catches your attention; don't you think?

The smell of a home can go either way, stinky or overwhelming.  There is a happy medium when it comes to smells in a home.  The smell of something baking is always attractive.

House plants do look attractive if they look healthy, half dead ones don't; I think I would notice the half dead ones before the healthy ones?

Art and books; not thought about that before, if the artwork is a large piece than I guess I would probably notice it.

Furniture placement wouldn't be something I would notice as it's that person's personal preference as to where they want things.

I do notice light fixtures, only because there are some really nice ones out there, but if they don't catch my eye, I wouldn't notice them.  I do however light a decent light source for certain tasks.
