Marc was a great host- detailed instructions and quick responses. The place was perfect for my girlfriend and I during our stay in Paris. Note that it is up 6 flights of stairs, but that probably helped me burn off the extra calories from the wine and crepes... very centrally located just a minute or two from the Odeon metro station, 5 min from the Seine, right by all the shops and restaurants along St. Germain. Would highly recommend.
