My girlfriend and I loved our stay at Rachel's. She, and her boyfriend Drew, were incredibly nice, and quick to respond to messages if we had any concerns. They even gave us suggestions for restaurants/breweries around town to try. The location of their place was right around the corner from public transit, and even if you wanted to drive to downtown it was never more than 15 minutes away.
We loved how peaceful, clean, and stylish (my girlfriend described it as "Bohemian-chic") their apartment was and enjoyed sitting outside on the deck just listening to the wind chimes and waterfall fountain. It was almost like sitting in a treehouse because you are surrounded by beautiful greenery and the neighborhood itself is relatively quiet.
Their pets were a highlight for our visit and a joy to have as roomies for our short stay. They were very laid-back, sweet, and at times comical (the cat Petrie loves to tag along on walks with his dog brother Banks, among other funny moments.) It was actually hard to leave them because they had become our little furr friends over the course of our trip.
Overall, we had a great time and we would recommend anyone to stay at Rachel's if they happen to be in Austin!
