Trying not to sound like a plug for any particular place, but there are shared/collabrative workspaces popping up all over the place.
The one I am most familiar with is Gangplank It is a location you can just drop into an do your work. There are no fees and you don't have to share anything. However the idea is basically that while you are sitting there doing your work, you have a casual conversation with someone else doing their work and you both discover and untapped opportunity and come together to fulfill it and make more $$$.
My local group provides basic desk/tables, free internet and free printing, and a free conference room - all designed to lure unsuspecting people into their midst in order to foster new business opportunities! These facilities have been donated by people/businesses with no expectation that you have to repay other than by being open to talking to and/or helping other people.
For more general ideas, google collaborative works spaces in your area and see what pops up. Also check up on any business incubator groups that may also have workspaces. There are also some subscription based groups doing the same thing, and I would also check into any maker groups in your area as well.
