Great location within 5 minutes of the trocodero and 10 to the Eiffel Tower. Plenty of shops and restaurants to visit. The room is well equipped and as described and pictured on line. You do need to climb a ladder to the mezzanine bed but if that is a problem the foldout sofa is very comfortable.
We didn't meet Sylvia but her associate Dominique checked us in and he was great. He covered everything in and around the apartment with passion and humour.
