I had been in Dallas for a friend's birthday. I was in the Legacy Park area and decided to stay at the Stonebriar about 11pm in the evening. The room appeared clean enough, except for the oily gooey substance on the back of the bathroom door, but I think it was grease for the door that some how smeared across the back of the door in the middle. After dozing off about midnight, I woke up at 5:30am almost 100% congested. I'd been in Dallas since about 11am, no allergy problems. I'm in that room for 5-6 hours and I have an ear and nose that is completely clogged and my eye is running. I noticed that my clothes had a faint mold/mildew smell in my suitcase after sitting in the room overnight with me. I can't lay down or sleep because my congestion. I try walking around the room to see if it will clear. No luck. About 6:30am, I packed up my stuff and went to breakfast. Immediately my congestion clears within 5 minutes of getting out of the room. Breakfast was OK, not $20 good though. Coffee is just ok. On to the good, the hotel is beautiful. The area is very nice and feels very safe. Parking was easy even with a wedding wrapping up. The greens are beautiful too.
