We were in Austin for a week, and Jason's place was great for that. It has everything you need, and it's in a laid-back, quiet area, too. It's about a 5-10 minute walk to the Clarksville "main street", which has coffee shops and restaurants. The check-in process was super easy, and Jason is really responsive to any questions you might have!
The place is about a 20 minute walk to downtown Austin (Congress Ave area), which we liked to do so we could see the different parts of Clarksville (lots of beautiful and historic homes!) and other neighborhoods on our way in. If you'd rather not walk, it's really easy to catch a rideshare from anywhere in Austin or the bus, too. Also, biking around here is awesome!
