Zhengran's place is just perfect for a family of four looking for a comfortable, clean, spacious, and centrally located apartment. It's a short walk from the RER, even with luggage and kids. Luxembourg garden is almost across the street. The apartment is super convenient to pretty much everything you want to see and do on the left bank and an easy Metro ride to the right bank sites. The sofa bed is truly genius-- it makes two separate twin beds and is ideal for bigger kids who need a little more space and do not like to share a bed. The apartment was roomy with plenty of storage and, although right around the corner from the action, peacefully quiet. Our hosts were great communicators (even though my phone malfunctioned!) and made sure we were taken care of. We would return again for sure.
