Discussion with my husband…
I have found that the word ‘suite’ means different things in different parts of the US.
What we have is 2 bedrooms, private bath, and a small kitchen area with a table and a futon for sitting. It’s a comfortable place to hang out and play games, have a meal. There’s no television.
The space is on a separate level of our home and has (or will soon) a wall and door between their space and ours.
Is it a suite? Or is it an apartment?
