The very detailed check-in information provided by Grace was spot-on. The valets were always quick and pleasant, every time welcoming us back. I am sensitive to noise and was pleasantly surprised that inside the apartment I never heard anything from any neighbors (whether above, below or beside us), with the exception of the next-door neighbor's front door slamming shut whenever they entered or exited (all the doors do that if you don't hold onto them).
I would consider the apartment an industrial-style with exposed beams, pipes, etc. It was most definitely a good-sized apartment, sparsely furnished with what I would consider lower quality furniture (but considering that you have a bunch of strangers constantly going through the place, it makes sense).
After we had checked-in, we had one question/issue. Grace responded quickly to our inquiry, providing the requested information. She then followed-up several times while we were there, asking us to contact her if we needed anything. That customer service was much appreciated.
Being walkers, we found the location to be perfect. There were some great restaurants within half a mile, and, for us, even the American Airlines Center, the sports bar at the Omni Hotel and the Dallas Aquarium were all within walking distance.
While there were always some types of smells radiating throughout the building - sometimes mechanical smells and sometimes food smells - it was never significant enough to cause 'discomfort', just significant enough to notice while waiting for the elevator or walking down the hallway.
We made use of the fitness center which, for not being an actual gym, we felt was very well-equipped. There were several treadmills and ellipticals, along with a rowing machine. There were free weights and weight benches/sets. There was even a room devoted to yoga and barre. And, of course, a TV to watch.
So, overall, a very good stay.
