Olivier is a great host!
All communication was promt and detailed. He even sent photos and videos of exactly what the outside of the building looks like from the street and how to pick up your keys from security and get into the apartment. We arrived very late (and very tired) and checked in around 2am and it was a breeze. The building is very secure (swipe cards provided to enter the building and to access the elevators). The elevators are fast so no big deal being on the 19th floor.
The neighborhood is vibrant with numerous restaurants and cafe's within a 5 minute walk (or less). Olivier even sent us a PDF with his favorite restaurants in the area and his favorite dishes from each of those places!
The view is indeed spectacular from this apartment on the 19th floor! In the apartment there is a laminated, panoramic photo shot from the balcony with each visible landmark identified. Very helpful information to say the least.
We walked to Notre Dame and the Eiffel Tower easily in one afternoon and evening , with a few cafe "pit stops" for wine and espresso along the way.
There is a large shopping mall right across the street which includes a very large grocery store (Carrefour), so it is very quick and easy to stock up on food when you arrive without having to take a cab or get on the Metro. The store has a very good selection of wine and the fresh fruits and vegetable selection is also very good as are the meats, fish, breads, etc, etc.
It was really nice to wake up the first morning and discover espresso pods and sugar already in the cabinet! We bought extra pods and left 10-15 for the next occupants to enjoy when they first arrive.
Highly recommended!
