I traveled to Austin for a conference with a big group of 8 people from my university research group. We stayed in two different places that we rented from David in different parts of the city. Both were comfy and well appointed and basically as advertised. David was flexible when we needed to arrange for a different arrival day (one day later) for one of the two places. We had a problem with the hot water not working, David sent someone over right away.
I'd be totally happy to stay in one of David's places again.
