Dominique was a lovely host and we really enjoyed our stay. The apartment looks exactly like on the pictures and was perfectly fine for all our needs. Dominique's niece was there on the day to meet us and hand over the keys and explain about how to work the heater etc, she spoke English as well (I myself understand a bit of French). We could leave our bags on the last day just until we had to leave Paris which was a huge help because otherwise we would have had to drag our suitcases around town.
I know the area itself from previous stays in Paris and it is just as lively and brilliant as always, lots of small boutiques and shops (I cannot recommend the rue Montorgeuil highly enough for food, we always got fresh croissants and baguettes) and beautifully close to all the major sites. It's only a 10-15min walk to either Notre Dame or the Louvre and with Chatelet-Les Halles the major transport hub you can catch a RER or metro to anywhere else.

I highly recommend Dominique and the apartment.
