Julia's apartment is extremely well located and only 1 minute walk from the RER-B line (Port-Royal station) which takes you directly to the airport or the main train stations.
Plenty of restaurants and Bistros around, and the area is very safe at night.
We were 10mn walk to the famous Montparnasse Tower and the Galeries LaFayette. 15mn walk to the Quartier Latin and Notre-Dame Cathedral.
We were also 7mn walk from our daughter's residence.
We rented a car on few days, and we could easily find paid parking places around.
In short, a perfect and easily accessible location in Paris.

Julia was very responsive and helpful to accommodate our check-in and remained available for any request despite her busy schedule.

The unit was clean, cozy, well lit, well aerated, and very functional.
It is fully equipped with Cable TV, Wifi, Fridge, Washing machine, Microwave, Toaster, Ironing board, Iron, etc.

The building retains its nice old characteristics of Parisian city buildings.
It is clean and calm despite the frequent ambulance sirens to the facing maternity hospital that did not bother us.
If you are not used to wood parquet, the squeaking noise maybe bothering...but that's its charm !
For those with big luggage, the narrow spiral staircases to the 4th floor maybe a difficulty as there is no elevator.

All in all, we were very pleased, and will come back again.
