Amazing apartment, amazing location. Right in the middle of the old city, the old city hall and Notre Dame Basilica are right there when you step out the door. Great restaurants and shops (and coffee!) within steps. Etienne was super responsive and even reserved a taxi to be waiting outside our door at 6:30am so that we wouldn't have to track one down ourselves to get to the airport.
There was some construction starting on the outside of the building when we were to stay there, and he also offered to put up additional curtains for extra privacy.
Overall great location, great host!
