We were a group of 6 who made use of every aspect of the house, cooking a few meals and enjoying the courtyard. The location is terrific, just a block off of Rue Cler, which has great restaurants, green grocers, butcheries, boulangeries, etc. It's a short walk from both the metro and Eiffel Tower.
Alexandrine and her husband really stepped in to try and make our experience pleasant. She's very sweet and really cares, going so far as reimbursing us for additional fans when a heat-wave hit Paris.
