Very average
This is an average Hilton property. Convenient to airport (you can walk to terminals), but not really focused on an excellent experience. This lack of focus is evident from the service in the restaurant (four meals and only one had good service) and from attention to details like a noisy ventilation system in the room.
We have stayed here once in the past and have stayed in the Hyatt also located at the airport, and after staying at the Hilton again, we would recommend the Hyatt, which has a free shuttle, though you can't walk to it.
For this visit we selected the HIlton because we had a business meeting at the hotel and Hyatt provided a cost for meeting facilities much more expensive than the Hilton, so if that is your need and cost is an issue, check out the Hilton. The staff did efficiently and satisfactorily handle all meeting related tasks.
