Ive seen the space, I like it. Very nice, it's relatively big (~ 15 ppl max) its within walking distance (across the street) of one of the best places for breakfast in the area, and on the route of 2 frequent bus lines.
About security (of the owner): It's not like you would not know who everyone there is (think LinkedIn, Facebook, Twitter), plus you could set in place some basic common sense safeguards (lock doors to your rooms, add those nifty security cables to laptops)
Security of tenants: Same as above, lock door(s) to office entrance, perhaps some CCTV at the door (cheap remote hosted)
Overall, I think it's a good idea, and I think you should do it.
