Sarah's space is as described, spacious and stylish, with all amenities you'll need for a short vacation in Austin. Restaurants, grocery stores and a brewery are just a short walk away, and downtown is also just a short Uber ride away. I enjoyed the stay and wouldn't mind to stay here again in the future.
The train is definitely something to keep in mind though. While the short passenger trains were not more noticeable than car traffic, there were also two freight trains coming by each night, which are a lot louder than you'd expect. We got somewhat used to them towards the end of our trip, but they're definitely something to keep in mind when you have a light sleep.
