We enjoyed our stay very much. The flat is exactly as Tiffany describes.
The flat is very clean and comfortable. It is small but absolutely sufficient and it has all you need. We stayed two nights with three persons and for that it is perfect. Tiffany offers some small snacks and drinks in the flat, some of them complimentary. There is a supermarket just around the corner and some fast food.
Going to the city is easy with Uber which costs around 10-13$. To the airport there is also a good bus connection, taking you 30-40 minutes for 2.50$ but you need to change the bus one time.
Visiting Austin, we would definitely come back as it Safes you a lot of money compared to the expensive hotels in town, and it is very cosy.
