Kay's apartment was great. Even though she was away she made sure everything was set up for us to access her apartment. It was very easy access to the rest of Paris. There is a metro stop very close to Kay's, but you also are within walking distance to Sacre Coeur Basilica. The apartment is very cozy and has everything available for you to cook, relax, and rest. The neighborhood may have a bad reputation, but we felt extremely safe and did not run into any problems or feel uncomfortable even though we would return to the apartment late at night. I would definitely stay at Kay's sunny flat with balcony on my next visit to Paris!!!
