Julien was an outstanding host. Everything in the flat was exactly as described and several food items, and a few additional "extras" we're in place to enhance our arrival to Paris. The flat's location is also perfect. The Metro stop is literally only a 3 minute walk even when our 3 year old insisted on walking. Notre Dame is a beautiful 30 minute walk along the Seine.
In summary, I can't recommend this flat highly enough. Julien is a fantastic host and you'll have excellent access to the entire city practically right out your door.
