"OPO Startups is located in a very cool, historic building on Main Street St. Charles with plenty of restaurants, coffee shops, etc within walking distance. The community is very close and I've enjoyed getting to know the other companies working out of the space. It's easy to see that the management team goes above and beyond to make sure everyone has a great experience!"

"Really easy to give this place a 5/5... It's got character, atmosphere, a killer location, and fantastic people. My company, Big Forest, utilizes the OPO and their resources all the time. They have high quality conference areas, secure, personal mailboxes, a small audio recording studio, and the convenience of color printing... All the essentials for getting a small business off the ground. I think the best part of all, though, is the sense of comradery between business owners, and the awesome events"

"Just spent some time while visiting St. Charles. It's a great space to work in with nice desks, chairs and amenities. Since it's downtown it's very convenient to get lunch or coffee in one of the shops nearby. Nice staff, always clean and very comfy. Would recommend it to anyone visiting or living in the area."

"Absolutely love OPO Startups. The space is beautiful and open with great working spaces, conference rooms, internet and coffee(!) The staff is very friendly, and the downtown location is very charming. Probably my favorite coworking space to date. Some things to note, be sure to bring all needed equipment (monitors, keyboards, etc.) - but this wasn't an issue for me as I have a thin travel monitor and set up which is perfect for coming in every day and setting up in 2 minutes. Love the space and look forward to coming back :)"
