Olivier’s place is small, but fully equipped with everything one could possibly need. While I never met Olivier in person, everything is very well organized. Check-In is very flexible and uncomplicated. Make sure to read the instructions after booking, and be ready for the small workout of climbing the stairs. The location was perfect for me between Montmartre and Arc de Triomphe, and with the beautiful Parc Monceau just next to it. I recommend using the Vélib city bikes for getting around – two stations are in immediate proximity.
