The apartment is on Place de la Sorbonne, which is full of students and interesting liveliness. It was absolutely quiet at night, so no problem sleeping — the best of two worlds. Kelly planned very carefully for any needs that we could have had and was readily available to advise us on the few questions we had. The apartment is filled with souvenirs from her travels, making us feel as though we were guests in her home, which, I guess, we were. As other guests have noted, there are a lot of stairs, but we got very used to them right away.
We have visited Paris dozens of times and never had so much trouble free fun as this, probably entirely due to Kelly and her apartment.
