Joe and Susan's place is great! It's super clean, has everything you could ask for, and then some! (They even stocked some beer and wine!) I rented it for my MIL and her husband when they came to visit us here in Austin. The location is perfect, close to everything, and so easy!
It has great art for decorations, you really feel like it's a home not just a rental. :) If you're coming to Austin and want to stay close (walking distance) but not in the middle of everything this is the perfect place.
Joe is a great host, has awesome tips for the neighborhood, and they even have bikes to use while you're out tooling around.
