The Airstream was wonderful and equipped with everything we needed (and a bunch of things we didn't know we needed! - Look for the shawls in the cabinets and the extra chairs) The private yard is great, especially with the wonderful outdoor weather we had this weekend.
Location wise - it is central for where we wanted to be. We went out in East Austin and South Austin and our Uber driver wasn't more than 10 dollars on Halloween weekend.
