Margaux's place was absolutely fantastic. It was nice, spacious, well-equipped, well located. While it's not in the core of the city centre, it is almost there and with an easy and accesible connection. The flat was, to be honest, perfect for me so I could enjoy the conference I was attending and also walking the city. I highly recommend this place.
And last but not least, Margaux is the perfect host. She was kind, respectful, easy-going and super responsible.
All in all, this place is a great place to be and enjoy Paris.
