I stayed at the Hampton Inn Detroit Airport for 1 night during a business trip. The rooms ate updated, clean and spacious. Room service is available and offers a decent selection. I ordered a salad for dinner which was prepared promptly and delivered quickly.
The only reason I am not giving a 5 star rating is the shower tub which seemed to not drain properly. I do not like to stand in a shower in ankle deep water. This however, might have only been a problem in my specific room (#611).
Breakfast is free with typical Hampton fare- a decent selection of hot and cold items.
Overall it is a good value and I would stay here again.
