I was asked to commit to a check-in time in advance, therefore when our plans changed and we arrived earlier (4 PM) there was no room ready for us. Air conditioning was not working so woke up during the night sweating with the windows open. Brewed Coffee is only available with the purchase of breakfast(12 euros). A concerning safety situation is that the room number is visible on the room entry card.
The bed was comfortable and the location is good for visiting Mont Saint Michel.
