I have nothing less than stellar things to say about the Matthews Public Library.
The most beautiful and serene library out of all Char-Meck's public libraries. You'll find it in the super cute albeit super tiny area that is downtown Matthews. Ample parking within the complex leading up to the library and behind the bldg itself.
I can (and have) spend an entire afternoon hanging out here. It can be a a few notches above silent in the early afternoon as moms w young children come in and out - I'm guessing before older siblings get out of middle/high school - and after 3pm there's usually a constant shuffling of feet and/or papers but all I do in both instances is slip on my trusty headphones and settle into my own space.
Choose from an array of comfy chairs, big desks for group work, and individual desks/work spaces. I must confess I very rarely seek out the assistance or info from any of the librarians (are they called library techs now? not too sure) so I can't rate their knowledge/customer service/etc. but I can tell you they're always in plain sight and accessible for patrons who do require assistance.
When weather permits, I sit on a bench outside or sprawl out on a blanket as I would at Freedom Park. I've seen a few of the aforementioned moms w young children do the same.
