Top Grafton Hotel Reviews

Renaissance St. Louis Airport Hotel

8/10 Good

"Parking isn’t free, this isn’t stated when reserving the hotel. You find out once you arrive. Parking is very congested."

Hampton Inn St. Charles St. Peters

10/10 Excellent

"Staff was absolutely outstanding! Friendly, professional, knowledgeable and eager to help. Rooms were clean. Beds very comfortable. Breakfast was awesome. Large variety to choose from. As soon as something was running low, the breakfast crew was refilling it! I definitely recommend this hotel. I know we will be going again."

Larkspur Landing Extended Stay Suites St. Louis Riverport - Airport West

8/10 Good

"The room is very spacious, bed is comfortable. There’s a kitchen with full fridge, am sure it was fully equipped but guests have either broke the utensils and whatnot so some are missing. It helps for long stays because you can cook meals. Housekeeping personnel ( the one’s I talk to can’t speak English). The lady that check me in is not customer friendly she is non- conversant most of the time, the younger girls are more friendly and very helpful."

Best Western Plus St. Louis West-Westport

8/10 Good

"First time staying at a Best Western Plus! The front desk clerks were friendly and appeared eager to assist. Our rooms were clean, minus a pair of 4XL woman's red panties found behind the bathroom door which i immediately threw in the hallway for the housekeeping staff to discard as they were still cleaning the room next door but they just pushed it into a corner, thus my rating of a 4. The ac worked perfect, the beds were confortable, the windows hung black out curtains, the breakfast hot food was adequate.. I esp liked the homemade yogurt, the surrounding stores were perfect had a Q-T for soda, ABC for adult beverages and the restaurant Bandana BBQ was ok...overall... I'd return and recommend.."
