We have stayed at Rio's place for 5 weeks, and we highly recommend it to anyone looking for a nice and comfortable place to enjoy Austin or to work. At Rio's place we have worked even better than from our own office! Wi-Fi worked extremely well, silent street and different areas where to work from (2 tables, couch, terrace...).
Also, there is always free parking on the street, and you can get to anywhere in the city in less than 10 minutes by car.
We have enjoyed Zilker Park almost every day with our dog, Finy, as it was less than 5min walk from home.
Sam and Rio have been great hosts, nice people, easy-going and very friendly.
We really recommend this place. For us, the best Airbnb place where we have ever stayed!
