nothing really. Trully mediocre

It is UNSAFE to leave your stuff in the room. Someone entered our room despite the do not disturb sign we always hang on the door. They obviously went through our stuff, and found our reserve bank carda we always carry with us when we travel. They are usually in a safe or as there was no safe in this hotel they were safely hidden and kept within our things in our room. They found cards and took pictures of them. They waited one day after our checkout and started charging our cards starting with $1800 and other amounts. Our US bank flagged the suspicious transactions immediately. But our other card was not so lucky and they stole 400 Euros and kept trying even after we blocked those cards. We know exactely where the cards were compromised because we never use those cards and the charges came spacifically from Nantes, so it was simple to understand who did it. I wish I can go back and confront them. Please do not stay there, find another safer place! It is already hell-knows-where from the city center. Just avoid at all cost!!!
