Marc's place is a great home base for exploring Paris. Its location is steps from the Metro and several great cafes for your morning coffee and croissant. Marc was very accommodating for our early check-in and easy to communicate with in general. He also sent us some great tips for nearby restaurants, etc.
I would note, however, that this is not a great option for guests with mobility issues: you have to climb several flights of stairs to reach the apartment and the main bed is in a loft accessible by ladder.
Would definitely recommend otherwise!
