I booked the apartment for a week for my husband, children and myself.
Catherine responded to all my emails very promptly and was extremely helpful.
The booking process was easy as was getting hold of the apartment's keys.
The flat was as described and very clean and well furbished. The beds very comfortable and though relatively small, the apartment is well designed. Though the main bedroom's window was on the street, it was surprisingly quiet at night.
The washing machine / dryer came very handy.
The location is also convenient as it it 2 minutes walk from the Louis Blanc tube station which is around 8 stops direct to the Louvre.
There are many restaurants around and the Gare du Nord is only 12-15 minutes walk away.
Overall, a very satisfactory experience and I would absolutely recommend this flat.
Thanks Catherine!
