We had a quick overnight stay at the hotel. We arrived at IAH at 9:30pm and only stayed until 7:00am the next morning.
The shuttle bus very helpful, we just called the hotel asking for a pickup and it showed up 10 minutes later. After check-in, which only took about 5 minutes, we arranged for for the shuttle back to the airport the next morning, again super easy and they offered shuttles every half an hour.
The hotel and room were in great condition, looked very new. The only negative, and it's small, is the size of the breakfast. They had some yoghurt, bagels, juice and coffee. It would've been nice to have some cereal for our daughter.
But overall, it was a comfortable stay and we'd stay here again when passing through Houston.
