We very much enjoyed our stay in Laurence's flat for a few days. If you are coming to Paris to do sightseeing, it is amazing how close this flat is to the main attactions in central Paris. The Louvre is 11 minutes walk away, many other things, like the Marais quarter are a healthy walk away, and for anything else, the Metro stops Les Halles/Châtelet, as well as Sentier will get you anywhere you need.
If you are a foodie (as we are), you will also enjoy the fact that the flat is very close to Rue Montorgueil, which is full of all types of food shops. E. Dehillerin is almost around the corner. Additionally, Laurence provides many useful pointers for good shops in her documentations.
The flat is as depicted. As many (all) accomodations in central Paris, it is not cheap, but it has absolutely everything you need during your stay.
Laurence is a great host - we had some special request around our check-in/check-out, and she was very helpful in finding a solution.
