Thin Walls, good parking
Pros: Stayed with a group of girlfriends before the Turkey Trot this Thanksgiving. Free parking which connected to the hotel was so nice. Plus, they had people working the booths to make sure you were either staying at the hotel or going to the casino. The location is literally in Greektown, perfect for dinner, Astoria, etc. Clean, modern rooms, definitely a pleasant surprise. They offered free breakfast and a casino credit too. 
Cons: The only thing that would have been nice would have been bigger bottled waters (small gripe, I know). They offered 2 small 6 or 8 oz bottles which probably would have been fine but would have been a nice touch since we were there for a run. And since it was the night before Thanksgiving, on either side of the room were loud groups clearly celebrating the bar night. I couldn't tell if it was thin walls or boisterous groups. Security was called 2x on the room next to us, and it took till past 4am for them to finally shut up. I know that isn't the hotel's fault, but definitely an annoyance. 
Overall, if I'm back in the area and need to stay the night in Detroit, I would return.
