A very welcoming hotel
This was my first visit to Texas and the hotel staff certainly uphold the State's reputation for southern hospitality. The staff is friendly and service surprisingly good for a hotel of this size. The Anatole was also the host hotel for a convention I attended so it was very busy during my stay. Saying that, the location is not the most convenient if you are visiting the convention center or downtown area. 
The rooms are at normal Hilton standard - clean and equipped with all the basics. The internet speed was not too bad however it did drop out a couple of times during my stay. Technical support were very quick to resolve the issue so it didn't affect my ability to work. 
The fitness center is quite big with a comprehensive selection of equipment. They also have group exercise classes, personal trainers and a spa. 
I recommend staying in the Tower part of the hotel, rather than the Atrium, especially during the busy times. I stayed at the far end of the Atrium on a higher floor and could still hear people at the Media Bar during the early hours. The Executive Lounge is also located in the Tower, and I would have used it more if I was staying on that side of the hotel.
I ate at the Media Bar 3 times and ordered room service once. The food was hit and miss, but the service excellent.
