My sister and I stayed at Camille's apartment and had a lovely time. It was perfect for two people and would be for up to four I think. The apartment was charming and relatively spacious, everything was clean, the beds were firm and comfortable, the shower had nice hot water, the kitchen was well-equipped, and the views out the windows were great. The street is nice and quiet even though we were close to many active areas, St. Michel and Rue Andres des Arts. It was very easy to go out and find the metro, or a bite to eat or shop, etc. The stairs to the apartment were a bit of exercise! but they didn't put us off. You would definitely need a bit of help though getting up the stairs with luggage. I would definitely stay here again, you can't beat the location and it's a beautiful old building! A really lovely Paris experience.
