The location of Julien's apartment is perfect. It is right by the Latin Quarter. A few minutes walk to St. Michel, Line B, the metro for the CDG Airport. You have wonderful bakeries, delis, restaurants, etc. in a few steps. You can walk to most of the Paris attractions.
Julien is a great host, very welcoming and attentive towards his tenants. The apartment is very clean. Julien has provided all the household items you might need for a few days stay, even chocolates and some fruit.
The location is very safe and quiet. We would definitely stay again at Julien's apartment.
