We stayed at Isabelle's flat 2 nights. Isabelle was present (when needed), very nice and helpful for us. The day of our departure we could stay 'till 14h30 in the apartment. The apartment itself was small but very clean, the bathroom was tiny and the shower had a very narrow entrance (so not very suitable for "bigger" people). The only pity was not to be able to use the fireplace. Isabelle has left a lot of good music and good books (also some guides of Paris).
The district itself, I found it calm and nice, metro 5 min. on foot; bakery and pharmacy open on Sundays. Surely, I recommend this place.
