The location you can't beat. It is in a great spot for tourists. We were in walking distance to everything we wanted to see. Notre Dame, Lovre, the Pantheon. It was amazing. The neighborhood was nice and quiet, it sat right off a main drag. The communication with Melissa was spot on. She was great at getting right back to me and accommodated us dropping off bags so we didn't have to lug them around Paris.
The only issue we had was that the Flat was not kept very clean. The bathroom was kind of dingy, the shower was moldy, and the towels were very old. In general the place could use a good deep clean and some new linens. It would really go a long way!
