Average Hilton Hotel with Little Nearby...
This is a large Hilton Hotel that seems to be searching for an identity. Is it supposed to be an airport hotel, accidentally placed just a little too far from Houston International Airport? Is it a business hotel, plunked somewhere in the outskirts of Houston near a mediocre shopping mall? Is it a conference hotel, with its vast (very empty!) open spaces? Whatever the plan was, it is totally unclear to the guest and leaves you wondering why this monolithic place is here with little else around. For me, it was on an international layover with 8 hours to spend the night and (thankfully) get on my way the next morning.
They offer free shuttle service to and from "IAH" airport, which is nice, but buckle in for the ride! By 15 minutes in, I began to wonder if we were going to Conroe, TX to watch a rodeo. This "airport hotel" isn't really that near the airport. You pass about 20 hotels along the way, so if you've got a short stay, don't waste your time taking the shuttle all over North Houston. 
Upon entering the hotel, the lobby is like some 1988 shopping mall with green painted beams soaring over wide open spaces and little carts selling products. I seriously thought I'd see the "Glamour Shots" portrait studio right there! The front desk staff was friendly enough, but in a very antiseptic way. I was not recognized as a Diamond member, nor did they seem to care about anyone standing in line along with about 40 crew members of American Airlines; obviously this is one of their official hotels!
The rooms are clean and comfortable enough, although the air conditioning is as loud as a jet engine. (Maybe that makes you feel closer to the airport??!) They have all the standard Hilton items, including the Peter Thomas Roth bath products, which I actually do like.
The restaurant and bar are so standard you feel like you've been taken advantage of once you get the bill, because the prices are not standard. They also have strict hours on everything, so even though it's a wanna-be airport hotel, if you arrive on a late flight, there is no room service, no restaurant, no bar and (ahem,,,!!) not even a mini-bar in the room.
On a good note, the shuttle does run twice an hour like clockwork, (because it takes that long to get to the airport and get back!), the beds are very clean and comfy, and there always seems to be a lot of hot water. On this stay, I couldn't get the shower to cool down, the water was still nearly scalding hot, even when the handle was on COLD. 
So if you are looking for a quick overnight stay like me, you're probably fine. However, I think there are several other hotels that are equally as nice, nearer to the airport and even a little less expensive. I wouldn't drive there again, even though the American Airlines attendants were quite a laugh on the bus...
