This is a superb place to stay in Paris. It's in a quaint old building in one of the best neighborhoods of Paris. The place is large, by Parisian standards. The living room windows open into a courtyard and the bedroom to a private driveway. I had a nice cross breeze going when I opened the windows. The two-block street is very quiet -- Paris can be very noisy! On the street you will find a couple of good restaurants/cafes, a bar which offers happy hour fare. It is located a few feet from metro Raspail, which is one of the main metro lines crossing Paris. Also, a 5 minute walk to the RER which takes you to and from the airports (a relief from traffic). There is a grocery store on the street. Try "La Mere Agitee," a little hole in the wall restaurant across the street that will cook you a traditional meal to order (let the owner know the day before what you want to eat) at half the price of a fancy restaurant! You will be staying at a street immortalized by Godard in the movie "A Bout the Soufle." There is a cafe by the same name on the street.
