Excellent hotel, poor location
I was booked into this hotel by my company for a large conference held at the convention center. Location was a big issue for me. Overall, my stay at this hotel was excellent, but the location caused the rating to go down. The hotel is stylish, clean, and comfortable. I had an updated room with a good view of downtown (14th floor), with excellent amenities and a wonderfully comfortable bed. I do not like the fact that there are no fitted sheets, but I find that in many hotels, and can only assume it is easier and cheaper to maintain.
My room overlooked the train track, and the noise was surprisingly high at times. If you are a light sleeper and go to bed early, then you should get a room that does not overlook the train track.
I did not eat at the Wolfgang Puck tower restaurant, but I did have breakfast and dinner at the hotel restaurants. Both experiences were excellent. The dinner was an elegant pizza, recommended by my waiter. The breakfast was good, as well.
If you are interested in sightseeing in Dallas or attending events at the convention center, I would not choose this hotel unless you have a car. Yes, it is rather close to the train station, which could be a plus if you are using it. Otherwise, it is a long distance to walk to restaurants and the convention center. Perfectly possible to walk it, but not a scenic nor a particularly safe walk.
