Sophie's place is in a great location. My daughter loved the "upstairs" lounge area and it was great to use the washer (and dryer) during our stay. All of the appliances are modern and there was a ton of natural light in the place. We had a travel disruption in getting to Paris and Sophie was able to accommodate those that arrived before we did. The master bed is European Firm (read: hard) which took a few nights to get used to. Also, it's clear in the pictures and we missed it, but there are windows on each side of the vanity mirror that allow anyone walking by into the kitchen to see into the bathroom/master bedroom.
Overall, it was a great place to stay for our trip to Paris.
