The other reviews are right, this really is one of the best locations I could imagine for visiting Paris. One block to the Odeon Metro stop, tons of restaurants, a grocery store nearby. There are a lot of steps, but being up high helps insulate you from street noise.
The air conditioning was much appreciated as it was very warm in Paris during our stay. The washer/dryer combo unit helped us pack light.
We never met the host, but were let in by an agent. The listing showed breakfast as an amenity, but we were never offered one.
