I saw or hallucinated an "Airbnb for office space" recently, but can't find it for love nor money (which is what makes me think it's a hallucination). I recently spent a bit of time looking for a desk sublet and it took way longer than it should have. Though I guess there's something of a thorny area with commercial lettings and the like, it'd still be nice to book a place at some startup in London/Paris/SF to rest my laptop when I'm next down there for a few days.
