Jon's house is really nice, it's completely self contained as well. The only downside is there is no washing machine on the premise (Jon does make this clear, but just something to be mindful of). You're about a 40min walk from downtown Austin, or about a ten minute drive. The area is nice and quiet, and you're next to the second university in Austin (St Edwards) which is a lovely green space and great for running around.
If you want to have somewhere literally as a base whilst you're out and about in Austin this is the place you want - you cannot go wrong.
