I recommend staying at Arthur’s place! It is right near multiple metro stations, bakeries, and restaurants. Everything is easy to walk to from here. We felt very safe with multiple gates to enter before getting to the actual apartment. Although there aren’t locks to the bedroom, Arthur’s family made us feel safe and as if we could trust them when leaving our belongings all day. The room itself is tiny but perfect for a couples getaway to Paris! We loved the window, which was huge and gave it a balcony feel.
