Sorry to hear about the water damage. More sorry to hear you didn't own a tenant homeowners (renters) policy. Not only would it have covered the water damage, but it would pay to rent you a hotel room, eat out, etc., while the work was being done (and Keith's Dad would tell you these things are CHEAP)!

As far as this specific loss, there may be a remedy for you under your landlords general liability policy due to his apparent "negligent entrustment" of the property to his clearly irresponsible designee. Find out which company/agency carries his coverage and file a claim. You have one for sure.

Good luck (and go buy that stinking renters policy...TODAY)!
