I stayed at this hotel with 3 friends during SXSW 2012.
The hotel was very nice and clean, with a good gym and laundry facilities. Breakfast was ok, but not fantastic.
Traveling to Downtown Austin will take about 15 minutes by car, very quick. But there is no public transport to be had or regular shuttle service. Taxies will cost around $20.
Travel to the airport is very fast as well, only 10-15 minutes, and the hotel has a complementry airport shuttle which will pick you up and drop you off.
Hotel staff are very friendly, helpful and man the service desk 24 hours.
