This building is no longer the Hyatt in St. Louis. In January of 2009 it changed flags to a Marriott. The Hyatt in St. Louis is 1 mile from this building, near the Arch.

My daughter stayed in this hotel for a pageant that was taking place there. She came home with bedbugs. They've been identified by an exterminator and we were told it would cost over $1000 to get rid of them. They turned up in our home four days after she got home.

No nearby bug reports
