I booked this spot for a week to attend the Austin City Limits music festival with my girlfriend, and also just to explore Austin a bit on the other days. The location was great- you're staying in a quiet, beautiful neighborhood while also being just a 5 min drive away from Downtown proper.
The host provided plenty of amenities- multiple towels and plenty of toilet paper come to mind (I only mention this because you think it would be more common, but I've stayed at a couple places where you'd think TP was more valuable than gold). Other benefits included on-site laundry, which was fantastic to have considering this AirBnB is located in a small guest house in the backyard rather than in the main house, and the bed was very comfortable with copious amounts of pillows to make yourself a nice throne with.
If you're looking for an affordable spot in a nice area while also being able to hit up the city in a flash, this is definitely one worth checking out!
