We stayed for more than a month and felt like we were leaving home when our rental ended. Made friends in the neighborhood; found a gym; ate ridiculous amounts of tacos; hiked and swam; haunted bookstores; did touristy things; and shopped at SO MANY thrift stores! It got the point where we didn't even need GPS to tell us how to get places.
Susan was super communicative and responsive and had things well in hand when issues arose. Not her fault that the weather gods decided to throw a hard freeze at Austin during Christmas (feels like 8F - brrr) but barely a blip in our vacation due to her gardener taking care of things like pipes and bushes and giving us clear instructions on keeping the water flowing.
It was a great place to work, too, with a dedicated office space. Cousins came to visit; having a second full bathroom attached to the second bedroom was a big plus.
Loved it. Hope it's available next time we're in Austin.
