I really enjoyed my stay in Mathilde's apartment and check-in/check-out could not have been easier. She even has lockers luggage for the travelers like me, who weren't leaving the city until later in the day.
Some reviews have noted the noise from the square, but that really wasn't an issue at all. Sure, you could hear some people but I really thought it added to the charm of the location. I will defintely stay here again.
