We only had one night at this hotel. It was in good condition, nice staff, and within walking distance of a train line and pretty easy walking distance to the Seine and Louvre. The key is an old school key that you leave at the front desk when you leave and pick it up when you get back. We were worried that we might not be able to get in when we came in quite late, as the front door was locked, but when we rang someone did come and let us in and gave us our key.
