Nessa is a great host! We stayed for two months in the house as a family of four, and loved it. The house is cosy, the terrace an ideal place to enjoy the Texas weather, day and night, and the backyard studio a perfect room for parents. We can fully recommend staying at Nessa's place. She also provided bikes, recommended good places for food and drinks, and even took us out to these places. We also enjoyed having drinks with her on the terrace. The location is excellent: quiet, but near all the nice things, e.g. Barton Springs Pool, South Congress, dowtown, the river, the green belt...
In short: enjoy Austin, we surely did.
