My 13 yr old daughter and I had a great stay on our vacation to Paris. The location was perfect for getting to and from all the key landmarks. The metro is super convenient but you could also choose to walk. While being right across from the Odeon Metro station and on the lively Blvd St. Germain, the apartment is tucked inside a courtyard so there wasn't any street noise. We also felt very safe in this neighbourhood. You can hear a little noise from other apartments - just like in any apartment setting. A small space perfect for 2 people.
