I suggest you avoid this hotel at least for a while...
I stayed at the CY Hobby on February 16, 2012 and I think I was in room 142.
The hotel is going through construction right now and it is causing some very large problems that they are trying to limit the disruption. That being said, I would not choose to stay at this hotel again. 
Pros: 
1. Close to Hobby airport. Less than 5 mins to drop off a rental car.
2. Bed and pillows were pretty comfy.
3. Room was recently remodeled. 
4. Staff seemed apologetic to the current state of the hotel
5. Quiet for a being so close to the highway and airport.
Cons - Hotel: 
1. Construction is reaking havoc on hotel operations: Check-In was in a conference room, Gym relocated to a dimly lit room, getting from one side of the hotel to the other required going outside.
2. Recently remodeled room was less than impressive. The AC unit was very loud and would NOT shut off at all. Mirrored closet didn't have door handles to open the doors. Room was very small. Hot water took forever to come on. 
3. Parking is very limited. Most of the parking is in front of the building which is very inconvenient considering you cannot enter the hotel in the front of the building. You have to enter the side or back of the building.
4. Room internet was very slow.
5. Only one working ice machine in the hotel and they could not tell me exactly where it was.
Cons - Location:
1. Scary neighborhood. Enough so that they have the parking lot gated off but apparently not scary enough that they ever lowered the gates! Makes you feel really safe.
2. Difficult to get to if you are not familiar with the area. It is a "You can see it but cannot get there from here," situation. It is located on a one-way access road that runs beside the highway. You need to exit the highway to the north of the hotel to get there or circle around on a different road to hit the access road.
It might be a better hotel when all of the construction is complete, but I was in a new room that still had lots of problems. 
No matter how much construction they do, it will not change the neighborhood. 
Hopefully their attitude toward their guests safety will change.
I am a loyal Marriott member and I wont be back to your hotel. Sorry...
