The house was as described -- it was very modern, clean and very convenient to walk to local coffee shops, restaurants, shopping etc. The alley was a bit noisy at night, La Mexicana Bakery is right behind the house and open 24 hours, but their breakfast tacos were great.
The host responded to texts and several issues were fixed quickly. However, on one day we had a smoke alarm beeping (to have battery changed) and it was about 6 hours before it was repaired, with no updates from the host during those hours.
Assuming that communication issue was a one-time problem, and not the norm for this host, I would recommend staying here for anyone who wants a clean modern home close to downtown Austin and the trendy Congress Ave. shopping area.
