We had a great time in Phillipe's apartment. He was very welcoming and very friendly.
The apartment was very clean and nice and just about 20min walk from Notre Dame. You can actualy see tour Eiffel from the kitchen window which is awsome specialy at night.
There is a small supermarket just next door to the building and also few restaurants to choose from if you want to take the dinner in the area. It is a quiet neighbourhood in the evning so if you choose to relax at night this will be a good choise. And if you choose to visit Louxembourg gardens, they are just 5 min walk from the apartment, from where you can also take the public transport (bus/metro).
