I've stayed with Kasa before in SF Bay Area and had a phenomenal experience with them in that location - was so impressed by how well-appointed it was, so decided again to stay in Austin. The apartment was ideally located for someone wanting to experience Austin for the first time and be near EVERYTHING on your itinerary list. You can't beat having parking included too. Kasa does a wonderful job communicating pre- and post and provide detailed instructions on how to have the best visit.
Our unit had some minor issues in bathroom which wasn't the end of the world and we found a workaround but still brought it to their attention upon leaving. They were very responsive and I have no doubt those minor issues will be addressed quickly by them ahead of the next guest.
I would definitely book with them again!
