My husband and I were in Austin for a conference (not at this hotel), but he chose this Westin for our weekend stay. He's a frequent business traveller to the area and likes this hotel because it's a newer property with a fitness center, business center (I didn't use either of these services so can't comment) and decent restaurant, plus they also offer free in room internet. We stayed on the Executive level (5th floor) and it was quiet, but not sure what, if any, other benefits come with staying on this level? Perhaps the free in room internet?
The restaurant (Urban) - serves some organic and locally sourced foods and has a few interesting entrees. We ate breakfast and dinner there and enjoyed both meals. I especially liked that the food arrived very hot! Service was quick, personable and efficient.
Location - As other reviewers have noted, you can't beat this location if you're looking to shop. The hotel is right in the thick of the Domain, which is an upscale outdoor shopping mall with stores like Tumi, and Nieman's. There's also an Apple store and a Microsoft store, as well as all the other usual chains. The hotel is right off the tollway and this makes it convenient to get to other parts in this area of Austin. An interesting, older area of the city to check out is the nearby Allandale neighborhood which has more unique shops and dining.
Accomodations - Nice "heavenly" beds with good selection of pillows, a duvet, a large desk for work area and a reading chair. Like the room, the bathroom was very clean and because this hotel is new, all the fixtures and appointments are modern and well done.
If you're looking for a shopping weekend in Austin, the Domain can't be beat and this hotel offers golf cart service to your choice of location in the mall if you don't feel like walking.
My only complaint would be the parking... It seems that the Domain shoppers use the Westin's lot to park in and this makes it a challenge to find a spot.
I would definitely stay here again.
