We had a nice stay in this apartment. Marion warned us ahead of time of the construction occurring and of the challenges we might expect with the key (as other mentioned in previous reviews).
The apartment is small, and there are some *very* cramped spaces to navigate the kitchen and shower areas. But for the location and convenience to everything we wanted to see, and the view of the Eiffel Tower, it was worth it. We appreciated being able to cook breakfast each morning.
It was very hot in Paris for two of our four days there. There are good quality fans in each of the rooms, but it's very warm just the same being on the top floor. Drink plenty of water.
Also, the apartment is on floor 6, and the elevator only goes up to 5. Keep that in mind for hauling luggage.
Nevertheless, Adrien and Marion were wonderful hosts, promptly responding to our questions. They adorned the apartment with fresh flowers and a bottle of wine to welcome us to Paris!
