Quite noisy outside during a weekend stay. You can hear conversations from the street and even cars passing by. Stairs are kind of scary - being 5' 10", I hurt myself multiple times trying to maneuver my way down from the loft.
However, great location with such great amenities, fully stocked with everything you need! We loved how clean and how easy the check-in and check-out process was, and we'd stay here again in Paris.
