We were 3 of us (my wife, daughter (13 years) and me) and we stayed in Laurence's lovely apartment. This is a perfect studio apartment and very spacious for Paris - its comfortable and spacious and well decorated. Laurence was a great host too - she greeted us and introduced us to the apartment and had notes for us for the cafes to visit.
The BEST part about this apartment is the LOCATION - its safe and quiet yet there are SO MANY wonderful cafes around the house - its just such a lovely area to live - walk to Louvre is about 20 mins.
The bed is comfortable - the sofa/bed for our daughter was huge and comfortable too - im sure 2 children can also sleep comfortably on the sofa/bed.
the apartment was also well equipped but as a very small negative - i think the apartment could have been a little better equipped with some water, room fresheners (for the WC area) but all in all for Paris - this was a GREAT apartment in a GREAT location
Laurence was also a very kind and helpful lady and guided us for our timings to reach the airport too :) which was very kind of her
we enjoyed our stay and we definitely RECOMMEND her apartment - thanks
