The location of the studio was very convenient - the metro lines nearby got us pretty much everywhere direct. Eugénie and René gave good instructions for finding the flat and were very responsive with questions. We arrived well before the usual check in and they were happy to accommodate us. The flat was clean and the bed comfortable. Good trouble-free wifi. Excellent water pressure and instant hot water. You'd do well to stay here for a visit to Paris.
(The by-product of being in the Latin Quarter though, is that the restaurants will be open late, there are street musicians serenading in the street (not all talented!) and the garbage trucks do come by early. But all of that will be very effectively blocked out if you close the windows and pull down the black-out blinds.)
