My sister, who owned the apt before me, referred me to Courtney. Courtney hops to action with little notice. She is quick to respond and flexibly mobile (meaning "Can I get your keys? Where are you?" And she was at my house in Bucktown within the hour to grab the apt keys.). She has also been creative and helpful with executing documents for my strict management office, using technology to our advantage, like Docusign. She's great and trustworthy. Thanks
