I understand however on the flip side I would tell the front desk. (I am sure you did.) Also, was there security/security guards? I have been to properties with them, and I would at least ask where they were the night of the break-in. Where there security camera and if so who was watching them? The hotel is not at fault but if some form of so called 'protection' was in place I would be asking the GM why it didn't work-especially on a longer term stay.
