My wife and I went on vacation to Paris in April 2017 for a week and wisely chose to stay at Anne-Marie's apartment. The location cannot be beat, and the Saint-Germain Des Pres neighborhood is wonderful. Fantastic cafes, shopping, markets etc. right outside your door. The apartment is very close to two Metro stops and is ideal for someone vacationing in Paris.
As far as the apartment itself, everything is up to date and very user friendly. The lift is reliable and easy to use (which is great for a 6th floor unit). Inside the apartment itself, the kitchen and bathroom are up to date and have everything you could possibly need. Both the living room and the bedroom have big windows that allow you to do some great people watching with a good view of Saint-Sulpice church. It is a great size for 2 adults.
The hosts are also very accommodating. Our flight arrived in the morning, and Anne-Marie allowed early check-in. Then, our flight was delayed, and Anne-Marie's son, Laurent, very graciously adjusted his schedule to meet with us when we finally did arrive. Recommendations on restaurants were also given, and if we had any questions or needs, help was quickly provided. We would definitely stay there again.
