Xavier's place had an amazing view over Paris. It was close to a large assortment of places to eat and drink and about a 5-10 minute walk to the subway.
Please note that while the location of this apartment on Airbnb appears to be closer to the 17th, it's actually in the 9th near Pigalle, so that was slightly misleading. The neighborhood has sort of a Brooklyn vibe to it.
The apartment had all of the amenities you would need. My only complaint is the temperature. Even with the windows open at night the apartment was very warm and uncomfortable at night, even warmer than the outside temperatures.
