It's marginally better without the window; I think a decent compromise would to darken, without completely removing, it; it is a little distracting in the original.
It's the age-old dilemma: are you a photojournalist, debarred from significant alteration to the scene as it was, or a photographer working only towards a final image which pleases you (and, perhaps, your audience).
I confess I tend very much to the latter.
