This place is pretty great. We were in Austin for the F1 races and I had 7 people in my party. The location in relation to South Congress is perfect. Which in my mind is a much chiller scene than 6th street. You are close enough that the walk is easy but far enough that it is super quiet. Also, the bar at the end of the street had live music and a deck out back. Great place to grab a drink on the way home and listen to some blues.
The house is spacious and clean. Tons of pots, dishes, etc for cooking (we cooked a family dinner and breakfast while we were there). The beds are comfy and the addition of the guest house is great for those who want it a little quieter than the main house (grandparents, children, or my old man friends who go to bed early). The pool and hot tub are nice and easy to turn on and off. the instructions for the house were detailed and the communication was clear. No issues with check-in and all of my friends really enjoyed it. My only con on the place is the yard could use a little work, but in the end none of us really cared. I would definitely recommend this place to anyone bringing large groups to Austin.
