We had a great time at Charles' place. The apartment was a convenient location to South Congress and all of the fun things to to in Austin (Barton Springs, Rainey Street, Dirty 6th, etc.) and only a 10 min or so drive from the airport.
The pool on-site was great for taking a quick dip to cool off and the taco truck next door was great for early morning breakfast tacos.
All in all, we'd definitely stay at Charles' home again!
