Our living room has a lot of furniture in it. While that makes it a little crowed, it's also super cozy.
My favourite part, by far, is the piano. We used to have it down stairs, but moved it upstairs when I got a new piano (well, new to me). It's great - I can play it for just a few minutes while the potatoes are boiling, or I'm waiting for Mike to come home, or just because.
