I stayed one night at Charlotte's Airbnb and it was awesome! She was super nice and we had some great chats. Charlotte gave me some great tips on what to see and where to eat. Her place was really clean and tidy, and it was really affordable. The location was perfect for me because it wasn't too busy, and there was easy parking. The only (very minor) downside was that there wasn't much to do in the neighborhood, but that's probably true for most places in the US if you're used to European cities (I am). Overall, I definitely recommend staying at Charlotte's place and would do so again if I stayed in Austin again!
