Emphasis on the walkable aspect. Did a lot and didn't have to use our car. Mary was very easy to get in touch with at all times and had amenities tailored to our planned activities (very much appreciated). An overall excellent host.
We gave a 4-star rating for value, but it is Austin, and the cost-of-living/price-of-everything is a little more than we would expect. Still, a host and a location that we would strongly recommend.
