I stayed at the Fairmont for a business conference. From what I heard, Fairmont is supposed to be a superb hotel.
That was not the case. It is run down and is in need of some updates. They had a few nice amenities, like a flat screen TV, and large rooms, but that was about it. The desk only had one electrical plug for my computer and the bathroom was nice, but needed some deep cleaning. The clock radio was from the 80's. I also noticed some spots on the sheets. They were clean, but had permanent spots.
I wouldn't pay that much to stay there for a vacation. It's not worth paying that much for the name. Go down the street to the Westin.
The hotel is also in a neighborhood without much to do. There were a few nice restaurants, but it is definitely an 'office' area of town.

The Fairmont Dallas is a great hotel, and for $149/night, a decent value. I highly recommend it to anyone staying in Dallas.
Facilities: The lobby is upscale and never too crowded. They have a nice pool & gym, as well as an upscale restaurant. A starbucks opened the day I checked out.
Rooms: Very comfortable beds and nice bathroom with ample space. They even had a walk-in closet. My only complaint is that the rooms could be bigger. It was a tight squeeze with 2 beds in it.
Food: I ate at a few catered events and it was very good compared to most other hotel food I have had in the past.
Service: Was great!! Everyone there was super helpful, room service was a breeze. I even had a small problem with the bill and it was corrected quickly with no questions asked.

A long review but trying to be fair as I am normally a big fan of this chain.

Went to Dallas for a special art exhibit & just to play tourist & the Fairmont was within 2 blocks of Fine Art museum & had a great rate offer for a suite. Perfect! Then I read the TA reviews and got nervous, but as first night was at another hotel, thought I'd keep the suite for major portion of stay & look it over day before checking in. Did & everything looked great. Upon check-in, suite I was shown was lovely but was advised that the new Gold floor was open and would I like to upgrade. Looked at that suite - wow, stunning! Took the beautiful new suite. Really outstanding decor and club floor was great for breakfast & nightly appetizers. OK, so for the negative: room A/C did not work very well entire stay; if it had been summer, oh boy, room would have been unbearable. Gold floors were still undergoing final "tweaking" so there were minor to major inconveniences: no elevator one day-hiked down 3 flights to lower floor; hot, scalding water in bathroom sink one morning (yikes!) and sadly, not very knowledge staff in Gold Lounge (although they did refer us to main concierge for help.) Response to all our daily issues/problems was polite, quick & fixed as much as possible, but some things, just weren't fixable. So, while room was great & hotel is lovely, not sure I'd stay again just because, heat, A/C, water are pretty basic requirements & having inconsistent basic necessities really cuts back on quality of stay. Too bad because the Gold floor is a real addition to hotel.

I booked this hotel via the hotel website and came up on a really good deal. It was a 3rd night free deal. So I paid $99 a night for the first 2 nights. The hotel was very nice and a good location downtown. It was actually the weekend of the Dallas/Green Bay football game. The staff was very helpful and I just really enjoyed the hotel. The bed was super comfortable. I would highly recommend The Fairmont, Dallas TX.
