My wife and I enjoyed our 2-night stay in Austin. Martin's place is conveniently located near the Domain and very close to I-35. The check-in process was easy, and Martin stayed in close communication before/during our stay.
The space is nice, with everything you need for laundry and cooking. The only con was occasional noise - we could hear the folks on the other side of the duplex, and the neighbors' dog barks. Everything else about our stay was great.
