Our flight was late due to technical problems, Marie was informed and she was there to receive us. The flexibility and reliability were appreciated.
Marie and John Paul are excellent, knowledgeable hosts and are willing to help and our conversation was most enjoyable. The neighborhood was the way it was described - the Luxembourg garden, the restaurants and shops are close by. The RER connection to the airport and metro Odeón are near. The apartment is well laid out, beautiful balcony, a firm bed and plenty of space for two people.
Our one suggestion is to write everything down. Identifying things with numbers such as restaurants does not help much because there are so many others within the same block. Writing down names and addresses of restaurants, grocery ; delis, laundromat on a map of the neighborhood (Google) will be more effective to tired, exhausted guests. The same goes with numerous attractions within walking distance.
We had a good time, will recommend it to others.
