Verified Reviews of Mainstay Suites

Below are the verified reviews from guests that we have booked recently:
"The Nicest Management I Have Ever Experienced!"
Overall Score5.0/ 5
The Mainstay Suites in O'Fallon, Illinois is a great place to stay. It is ideal for groups, school trips and extended stays. The building appears brand new. It is in a great neighborhood that is close to the interstate, shopping (Target, Home Depot, specialty stores), restaurants and other retail venues. The location is convenient to downtown St Louis and avoids most of the traffic from the more crowded west end of the city. Every inch of the property is spotless from the parking lot to the rooms. The rooms are spacious with high ceilings, full kitchens, lots of closet space and very comfortable beds. The shower is nice and spacious and has plenty of water pressure and hot water. The breakfast area is huge with plenty of seating for large groups and has a nice fireplace. The included breakfast is tasty and comparable to a Hampton Inn or Hyatt Place breakfast. The management and employees are super friendly. I left after an extended stay and actually miss talking to the people that work there. Rarely do I stay somewhere that I miss the employees of the hotel! The owner is fantastic. We forgot an essential piece of equipment in the hotel and he drove it to us in downtown St. Louis and would not accept payment for doing this! We were stunned! These people sincerely care about their customers. I recommend the Mainstay Suites without hesitation!
