Nice Lobby. Nice bar. I liked the Concierge Lounge. But, it's right on top of the freeway!
Pros:
1) The lobby is nice. But, it does not reflect the quality of the rooms. 
2) The bar was pretty nice and had a beer on tap for this beer snob (Hopadilla IPA). 
3) The food was yummy and reasonably priced.
4) I liked having breakfast in the concierge lounge.
Here are the cons:
1) As mentioned in other reviews, it's right on top of the freeway. I heard sirens like they were right outside the room. And I was on the 14th floor. So, don't expect peace and quiet.
2) The first room I was in had a soaking wet floor. There was also some gooey mess on the coffee table. It also smelled old. About time for a renovation. The room they moved me to smelled like cleaner and sewage (when the toilet flushed). Maybe just a stroke of bad luck? I packed up a 3rd time and changed hotels the next day.
3) After the issue with the floor being flooded in the first room, I was "upgraded" to the 14th floor. I lost my junior suite for a smaller room on the 14th floor. So, I am "upgraded" just because it was on the top floor? I didn't understand that logic by the front desk.
I have 2 more weeks of business here in Houston. But, I will not be staying at the Hilton Houston SW.
