Is O Fallon MO a good place to live?

O’Fallon is a great place to live, with plenty of new construction, outdoor activities, and shopping nearby. However, it is a very big suburb and it won’t offer that urban lifestyle that’s easy to find in St. Louis City. It is also about 30 to 40 minutes outside of downtown St. Louis, so if your commute is into the city or even Clayton, it will take you longer to get there. Despite all that, O’Fallon is a gorgeous part of St. Charles County and has so much to offer if you’re moving to this part of town.
