I don't have a specific place, though I usually write sitting on my couch in my condo. I definitely do my best writing when I'm alone and it's relatively quiet - I can either have a WC episode that I've seen a million times on with the sound low or some instrumental music.
Nope, I can write anywhere, on the boat, in the car, on the train, in a coffee shop, on the couch at home... I always have a laptop or old fashion note book with me, so....
