Columbus Ohio Property Managers for Small Apartments MFR

Hi all, I have done some research in the Columbus, OH market as far as property managers for a 12 unit 1 bedroom 1 bath apartment. I have narrowed it down to The trinity Group at HER Realtors and Northpoint Asset Management. Has anyone worked with either of them to give me some feedback on their reputation and business model?

Your information is highly appreciated.
