I haven't fully decided--it's not going to be free, for sure. Probably, people will pay me and I will pay the landlord, since that seems more convenient, but I could easily be convinced to just have people pay directly instead.

As I said on the page, the goal is not to make money, so any payment will just be to cover costs. I'm not quite wealthy enough to just give away the space for free yet :)

My point was more that if one person flakes for whatever reason or a startup drops out and you're financing the entire thing directly with the rent paid by the rentees you're in for a world of hurt unless someone comes up to cover it... I assume if you pay for it and then the rentees reimburse you the worst case is you lose money; not that people end up homeless.
