I stay at the JW in Houston on a monthly basis for business. The property is great. If you are looking for a perfect location(across from the galleria), great service and ambiance then this is the spot.
I have stayed at other properties in Houston and it is a challenge to find a non-smoking hotel and a hotel where you don't hear a peep from others rooms.
The staff is always hospitable, especially the assistant manager Jason who will go out of his way to make your stay memorable.
I am a permanent member of the JW Mariott Houston fan club.
EXCELLENT.

This is an awesome hotel, right across the street from the Galeria mall. The room was nice, clean and the bed very comfortable. The fitness center rivals that of any health club and the pool is indoor/outdoor. Overall, great hotel in a nice area. I highly recommend it.

I've worked for luxury hotels and would rate this one average for it's category. The rooms are the newest Marriott rooms with a sleeker, modern decor. But it doesn't stand out in any way, very cookie cutter. The location is good for shopping and getting a meal. The lobby is nice but not comfortable to sit and have a cup of coffee or read the newspaper. Room service and staff were good but not great. Geared towards business travelers, not vacationers or shoppers. No standout bar or restaurant. Comfortable, clean and updated...no surprises. A good value for the money on the weekend.

Not up to other JW Marriotts I've stayed at. Public spaces seem to be in need of renovation. Restaurant closed, in favor of dining at lobby bar.
