Laurence's place is an unusual and very attractive loft space. It is on the American 2nd floor (French 3rd), but there is no apartment overhead, which is lovely. It is in the 13th arrondissement so not in the very center of Paris, but only a 2 minute walk from the high speed metro line 14 which gets you there in just a few minutes. It's also very convenient for work at the BNF--not a long walk or just one metro stop. Laurence is very nice and thoughtful, and was easy to communicate with. I arrived in the evening on the train and she greeted me in person and showed me everything very patiently even though it was late. I very much enjoyed my stay and hope to return.
