We have spent a nice weekend in Sophie's appartment. It is very well located in a nice and vibrant neighborhood. There is a metro station closeby but you can easily walk to city centre as well (we made it in 30 mins to Louvre Museum). The appartment is small, cosy and functional, perfect for a weekend-trip. Sophie is a nice and friendly host; she welcomed us at her place and kept in touch durinh the weekend. Good organization and communication!
We definitely recommend staying at Sophie's place.
