I had the exact same thought.. "doesn't Google maps already solve this problem all over the planet?" About a decade before I remember using Google's 'hub'(I don't remember what it was called) in a couple of EU capitals. Free, super fast internet, clean spaces, free desks, whiteboards all around. You had to pay if you wanted a 'room with a door' and a projector, but apart from that if you didn't mean the eavesdroppers it was perfectly fine (and relatively quiet).
