Just had the family (2 adults, 2 kids - aged 11 & 8) stay at Charlotte's apartment and we had a wonderful time. The apartment is cozy with rustic charm - the floors are original and creek but it was fine. The kids were able to practice piano. The kitchen - while tiny had everything we could want and was probably the best stocked of any Air BnB stay I've ever had (not that we cooked what with the French cooking available in the neighborhood). The location was perfect - central to walking to all the sights and / or quick access to several Metro stations and bus lines. One thing to note - the bathroom is small, I am 6'2" tall (1.94 M?) and 205 lbs. and I barely fit in the shower. If I were half an inch taller or even a little wider it would have been a challenge. As it is, I was able to make it work, but you should be aware.
Finally, Charlotte was fantastic responding to my questions and making suggestions for our stay. All and all a great stay and a great space.
