We stayed there as it was a new Hyatt and wanted to check it out. Location is awesome; downtown and highly walkable. We even went on the Austin Light Rail (who knew Austin even had a Light Rail) as it was one block away from the hotel.
The hotel is great; lots of natural light in rooms, especially those on higher floors as they have floor to ceiling windows. Everything is clean and modern. Front desk is helpful and cheery with lots of eats and drinks suggestions. I like this Hyatt better than the Town Lake location, especially because the rooms are much bigger, with a separate area for TV and sitting.
