I would also look at the fact that the first told you there wasn't an apartment
available. Guessing that they knew you wouldn't consider and 3rd floor
apartment either way, so maybe he is having to move say for an job.

Or hoping this isn't the case but say he is an government worker and
is not liking the looks of the job situation there and is moving in with
family because of what is going on. There are many reasons other
than a problem with the apartment that he might be moving.

I'm going to say that in my opinion, someone up higher has decided
you needed an break and this is it.
