Pear Tree Inn St. Louis Airport
Shuttle to airport was great and then shuttle back to pick up my car was also great. Nice to be able to park at the property for a few days.

Hilton St. Louis Airport
The room was clean, the staff was nice, and the hotel had a good atmosphere. The lobby restaurant/bar was busy but not overly crowded. The food was good. The floors with the rooms are quiet.
