We (3 girls) had a wonderful week-long stay in Jerry's apartment in Montmartre. Jerry was a terrific host and made it easy for us to get to the apartment and was so helpful about general recommendations for Paris. The place was very comfortable and clean and conveniently located. It is just down the street from a metro stop, in the same building as a patisserie and near two grocery stores. Sacre-Couer is a pretty, 20-minute walk away.
