Whoever would sleep near such a thing, probably needs sleeping pills.
Fun to look at from a distance, but probably not very healthy close up. With an average distance of about .83 ly between stars an awful lot of radiation would saturate the cluster - Not to mention the occasional supernova (I calculate about one every 750,000 years in the cluster) which would sterilize everything. Since evolution occurs on a lot slower time scale than the rate of supernovas, this alone would probably be enough to preclude the development of life.
