I doubt that there's another hotel that offers such a dead-center, unobstructed view of the cool Dallas skyline from its rooftop pool. Granted, the pool itself isn't huge, and on a warm, sunny day, it'll be a crap shoot to get one of the lounging chairs. But it's still worth it.
NYLO Dallas South Side is a little bit off the beaten path. I get the sense that this section of Lamar is turning into a bit of an entertainment district, but it really is a tiny one compared to the many others around town. It's very accessible to downtown and the highways, so location-wise, it is a good choice.
The decor is modern/quirky and makes good use of the features of this building, which I suspect used to be used for some industrial or warehousing purpose way back when. I loved the high ceilings and how they dampen any noise from heavy-footed guests upstairs. I did hear some voices from the adjoining rooms, but it wasn't terrible. In fact, I requested earplugs -- something I never do -- because there were a couple of wedding parties at the hotel on the Friday night I stayed. Slept beautifully.
I'm not a big fan of the use-a-key-card-to-activate-room-lights feature... I get it, it saves a lot of energy. But given the fact that most guests, even if they're by themselves, are issued at least two cards, it's a gimmick that's pretty easy to defeat. Unless it's the middle of the night, in which case it means fumbling for the stupid key card in order to see one's way to the bathroom. That's really the only thing I didn't like, and all in all, it was 5 seconds worth of grumbling from me... not a big deal.
Loved the free wireless, didn't mind the valet (the charge is a LOT cheaper than in other cities, or other parts of this city) and thought the staff members were great. I don't know much about the NYLO brand, but I hope they're able to expand to several other cities. I'm a fan.
