Harold's apartment was the most lovely and spacious we had stayed in with our family of 5. Although one child slept on the sofa bed, having space in the lounge/dining area and ample space in the main bedroom, it really helped for us all to have option of having room to move, or spread out when we were relaxing.
The location is brilliant, with a short walk across the bridge to the Louvre, the shopping strip of Rue De Seine on the doorstep, and grocery stores, or bakeries, and restaurants to choose from. A short walk from several tube stations made it easy to get around to the locations we wanted to.
A special thanks to Bruno for posting back our son's phone within a day or two of us leaving. That was much appreciated!
