Stayed here for 6 nights on a business trip. Good price, very convenient location for me - I booked here because my training facility was 1 street down from the hotel, it is very close to the airport, I am a Marriott Rewards member, and I was given a discounted rate since the training facility has a deal with the hotel.
Staff were very friendly, I had no problems checking in and out.
Hotel room was much better than I expected, I had a suite, with full and functional kitchenette. Lots of space, cleaned every day - it really was very nice.
Hotel had many great services and facilities, unfortunately I did not get much chance to try out any - indoor pool and jacuzzi, grocery services, along with hospitality activities on evenings - they really try to make your stay as confortable and entertaining as possible.
Wireless internet was fantastic - especially because it was free! I had read a review before I booked of someone complaining that it never worked, and that the reception area provided no assistance to him. Well, this is true - I could not connect either when I got there, and the reception personnel could not assist. However, this isn't their issue to deal with, since the free internet service was not provided by the hotel itself, it was supplied by some outside organization - I'm not entirely sure how it worked exactly. But nevertheless, there is a brochure card on the desk which advertises the free wireless, and on it, there is a number to call for assistance. I called, explained the issue, and I was surfing within 5 minutes of placing the call. Never got disconnected over the entire 7 days I was there.
Lots of eating places nearby - fast food like Subway, McDonalds, Popeyes, Pizza Hut, Taco Bell, etc are all within a couple minutes drive. There is a good sushi place called Ichibon, just about 3 minutes drive away, along the way to Greenspoint Mall (which is about 5 minutes drive away). The Mall is not great for shopping, it's moreso good for quick food from the food court, and basics.
The area is reported to be fairly dangerous (referred to as "Gunpoint" rather than "Greenspoint"), but as with anywhere in the world, so long as you are mindful about where you are and what you're doing, everything should be just fine. Just don't go walking out in any dark lonely areas at 11 pm with bright gold jewellry from head to toe - all it really is about is just using some common sense. I didn't have any problems while there, and never felt unsafe.
It is some distance away from Downtown, and the bigger shopping and entertainment areas in Houston, so I would not advise the location to anyone who intends to be partying up a storm. However, if you need somewhere to rest your head and take a shower, which is close to the airport, has everything you need within a few minutes drive (dining, WalMart, etc), and don't really care to be out all night living it up, then this is a great option.
If I return to Houston to recertify my training again in 2 years, I will be staying at this hotel again without a doubt.

The 2 bedroom suite was a great arrangement for our family of 4. With rooms separated by the living room/kitchen the kids could stay up late watching television without disturbing us. The rooms were well-appointed, and clean. Breakfast was great - daily selection of eggs, sausage, potatoes, french toast, waffles, cold cereal, fresh fruit, yogurt, coffees, juices, milk, etc. Staff was friendly and responsive. Location close to the airport and expressways was ideal for getting around.

Good location - half way between Greenspoint and Intercontinental Airport. Ideal for both, and also near the top of the Hardy Toll Road which made it easy to go downtown in the evenings.

Staff on the reception desk was friendly and helpful at all times, and breakfast was well-stocked and served in clean and comfortable surroundings.

My room was very comfortable, with quiet air-conditioning and comfortable areas to work and rest. TV was somewhat "old style" with interference patterns on all the channels, but sound was OK. Wireless Internet worked efficiently and at high-speed over the week I was there, with the exception of 30 minutes when it was down for "maintenance" (at 5pm on a weekday?).

Laundry worked well and didn't have to wait for machines either time I used it.

Service felt like it was a bit above average for this kind of hotel. There was a card in the room where you could order groceries for the staff to go shopping and get what you wanted at cost. I did my own shopping at a grocery store in Greenspoint, which wasn't the most pleasant experience ever, so I can understand why that service would be useful. There always seemed to be some kind of food in reception in the evenings - if you ate a big meal at lunchtime, that would probably be enough to see you through the evening.

I don't normally stay in this area, but was working with a customer at Greenspoint for a week, so I was glad to cut down on the commute time. If I was working in the same area again, I would definitely come back.

I was asked to review and sign a "noise policy" form at check in, which stressed "11pm curfew" and a "no party policy". However, sounded like a marching band above our room most of the night. Called front desk to complain, noise abated for awhile, but came back. I suspect this was due to poor soundproofing rather than any real "party" going on. I have stayed in over 100 residence Inn properites in the USA, and while the design of this hotel is very typical of this brand, for some reason the noise from above and outside the room was ridiculous. Room was quite clean, but no sheets provided for pullout. Breakfast was below average for this brand. Close to airport, but otherwise there is nothing close to this place in terms of food/gas/shopping.
