Absolutely stunning bedroom on the upper floor, wow! That was a once-in-a-lifetime stay.
The rest of the unit is really beautiful too. Quick note- there are some great kitchen appliances, like a kettle and an espresso machine, but no coffee grounds / grinder or tea bags are provided so make sure you bring your own.
Also, there is overnight parking available nearby at an underground parking lot, the entrance is off Rue Pierre Olivier Chauveau. (Type "5 Rue Pierre Olivier Chauveau" into Google Maps.)
