First of all the hotel should provide a "hotel-run" shuttle dedicated to guests from the parking lot directly to the Mont's entrance. Even with minimal luggage, it was incredibly inconvenient to walk from the bus drop-off to the Gate and then on the cobblestone street up to the hotel !!
Secondly, to access our reserved room, we had to go through a maze of stairs, outside on the rampart, through some room being repaired & then again down some more stairs.... For a so-called "high-class" hotel, this was totally unacceptable. A very disappointing experience.
One piece of advice to future travelers: stay in a hotel which is not "intra-muros".
