My fiance and I adored the Tiny House! It's super cozy, and perfect for two people who are mostly out and about, and just need a place to crash for the night. The place is clean and comfortable, and situated within a 10 minute drive of most of the popular areas of Austin, such as Rainey St, South Congress, and Downtown. The host even provides a binder of local recommendations, which we took full advantage of! I do want to note that we never met Sean or Brad in person; you self check-in when you arrive, which was really convenient for us because we landed in Austin at 11pm.
One thing to note is we had some trouble with the wifi: our phones wouldn't connect half the time, and when they finally did, the internet was pretty slow. Power cycling the router repeatedly seems to help :)
