I stayed at Dan's place for the week of SXSW 2017, and travelled into Austin every day. It's a great place to stay, even nicer than it looks in the photos - it's a bright, open space with a fully equipped kitchen area, comfortable living space and mezzanine bedroom. Dan made it very easy to check in and out, and the provided made it easy to find everything I needed in the area.
Before coming, my concern was how I was going to get around, so I'll write a quick note about that - although it's not central, it's very accessible to get to the downtown area from here - 45m walk or 15m bike ride on quiet roads, or 10-15m on the 803 express bus. I did all of these during my stay, and all were pretty easy.
