How do you find a temporary office space in bay area / NY?

We're trying to build airbnb for commercial real estate, but have hit some kind of roadblock in our thesis, so I thought I'd turn to you guys for help. I want my users to book office space entirely virtually. However, people I have talked to (friends and family members) insist on visiting the place before renting it, even if it is for temporary purpose (1-6 months). Since many of you are entrepreneurs or decision makers (my target segment), what would it take for you to have entirely virtual transaction for a temporary office for team size of 1-10 people? How do you do it today?
