The first thing that comes to mind is the Map Building on Valley Street in Maplewood.
There are a lot of small companies based in the building and I've heard of some of them subletting space.
I started here: https://mybranchoffice.com/
Great location, paid for the time I used, great space.

Looking for a desk in an office environment for my startup
We are a Health & Wellness startup and are looking for someone in the community to help us by offering a desk in an office or a somewhat professional environment that we can use part time during the week.
Really appreciate your help ahead of time...
