I recently went from a home with all carpet (except kitchen) to a home where only the bedrooms were carpeted.
I agree, it seemed less homey, and very echo-ey, like I was in a cavern! Like in the movies where they yell "Hello!" and it comes back "Hello, hello, hello!" lol!
It helped some to put down a few area rugs. You can find some inexpensive at
Walmart or Big Lots.
Then you can use the area rugs as an "anchor" for the furniture, if that makes sense.... something to place your furniture around.
I find myself cleaning the floor more often too, but my floor shows footprints easily, if you have a textured tile that might not be an issue.
Good luck!
