I stayed for about 1.5 weeks at Rachel's place and it was an absolutely lovely experience. The apartment is incredibly bright, and well decorated, and Rachel and her husband were incredibly communicative throughout.
I felt very at home in the apartment, and it was nice to look out the window into the lovely back yard. Also enjoyed some daytime walks through the surrounding neighborhood.
They were very accommodating of the travel plans I had, and it made for a great spot to base out of while in Austin. Hopefully I'll get to spend more time there in the future & would recommend it for your stay!
