I cannot recommend this place highly enough! Christophe was a fantastic host. He even let us drop our bags off early since our flight landed at 7:00 on the day we were going to check in. He also let us keep our bags there on the last day so we could explore the city a little more. The location is fantastic. Lots of greats restaurants and bars, not to mention the patisseries and boulangeries, and the metro is nearby. He was really quick to communicate with us when we had a problem with the wifi login and it all got sorted out.
The apartment is immaculate and has everything you could want. We were three adults, but it would work with a family with 2-3 children, too. The kitchen was well appointed, bathrooms excellent with great water pressure and it was a great place to spend time together when we were not out exploring the city.
Stay at his place if you get the chance!
