I am at the Nice Le Méridien spending my first night of a two night reservation. Both nights are separate bookings independent of each other and made with points.
The hotel and room is not up to standard. This might be the most disappointing hotel I have stayed at in a long time. I would prefer to check out tomorrow without incurring a penalty.
The room phone does not work and I cannot call marriot customer service. The manager is “not in”. The front desk has no authority to make any concessions and are offering a downgrade to a room with a working phone and perhaps a bathroom door which actually closes shut.

What are my options? Thanks for your help.
