My wife and I were in Austin for a wedding and wanted to get in early, as ATX has been on our list of places to visit. Bill's place is perfect for a couple looking to explore Austin. The space is very well appointed and has all you need--big comfy bed, sitting area/room for luggage, kitchenette, toiletries/towels, etc.
It's maybe 10 min walk to S. Congress Ave which has some cool shops/restaurants and another 10 minute walk to 1st St. which had some nice spots as well.
To get to the parks and downtown area you'll want to Uber/Drive but this place was perfect. Bill was super accommodating with check-in (even got to check-in early, and he had mentioned we'd be able to drop our bags off even if we couldn't fully check-in early).
Great spot, highly recommended!
