Corto's place was perfectly located across from Notre Dame and was within walking distance of public transportation! It's also close to a lot of restaurants and souvenir shops which closes late so that was a definite plus! I would highly recommend as it's a great location and in a safe area. There's policeman constantly on guard right outside his flat, so we felt safe walking in late at night. His place had a great view and had everything we needed. Thanks Corto!
