This place and this host were the crème de la crème of Airbnb.
The flat was SO CLEAN and classy. There were great touches throughout including easily accessible extra linens, considerate and higher-end toiletries, laundry detergent that was was scent-free (strong scents are not my bag.) The host was in contact enough to feel cozy but not intrusive, and each interaction was polite and professional. The location was awesome, I could walk to almost anything but the area was quiet and peaceful at night. A parking space, people. Huge bonus.
So happy to have found this gem, and hope to stay again soon on my frequent business trips to Austin.
