The view from the balcony was absolutely spectacular! I have stayed in about 15 different places in Paris over the years and there is nothing to compare with a panoramic view from the Louvre on one side, Sacre Coeur in the distance, the spire of Sainte-Chapelle, and the Notre Dame on the other. I spent happy hours just sitting on the balcony watching the river boats sail by. It is a perfect location.
Communications with Etienne-Marie were easy before and during our stay and his written instructions were excellent for accessing the front door. It's great to have an elevator almost to the apartment, with just one floor to climb by stairs. Etienne-Marie met us on the 5th floor and helped us up with our bags. The apartment is very large for the neighborhood, with lots of choices of restaurants and a good supermarket about 5 minutes away on foot. The beds were comfortable and the WiFi worked perfectly. I hope to come back and stay longer than 4 days.
