The Hilton Frontenac is a great hotel in the middle of St. Louis. When we first arrived we were a little apprehensive as it looked like the hotel was fairly old but it did have a very classy old-world feel to it. We were impressed once inside as the hotel has been well kept and updated throughout the years.
Due to a conference being held there, the only rooms available were in the executive suites. This turned out to be a great find. The room was very spacious and we had access to the executive lounge. In the lounge, they had free wi-fi (there is a charge for wi-fi in the rooms), breakfast, appetizers in the early evening, dessert at night, and soda and water available all day long. We had a toddler with us and the lounge was wonderful to grab him some quick food or drink without costing us anything extra.
There was a restaurant on site and room service was also available, but we did not try out either due to having access to the lounge.
