First of all, Carolina and Emiliano are both incredibly sweet, thoughtful and hospitable. The casita is very cute, thoughtfully decorated and cozy. Bonus points for having an NES for your entertainment should you need it. WIFI was solid in case you're wondering.
Without question it was my favorite airbnb stay yet.
The casita is located just east of downtown (about a 10 minute drive) and not much more than a 20 minute drive from anywhere else you might want to visit in Austin. If you find yourself at a loss for places to see the hosts will happily provide recommendations.
10/10 would sleep in again.
