We loved our stay at Marine's place! The apartment is very cute with great windows overlooking a charming and lively (but not too lively) Parisan street. The location was very central and allowed us to walk to easily to Bastille and through the Marias and even as far as Norte Dame on a nice night. Many nice boulangeries and restaurants in the area.
We were in good communication with Marine and her friend who gave us the key.
The bedroom and bathroom are definitely cozy but worked fine for my husband and I who are average sized and stayed for several nights.
