I spent a great weekend in Paris and in Stéphanies apartment with my husband and daughter at 18. We walked a lot during the days, which was easy since the apartment is situated in the middle of everything. Notre Dame, Le Marais, Quartier Latin and the charming Boulevard St Germain with lovely cafés and shops. It's also very close to the small Place Maubert, only five minutes walk, where there is a nice market some days of the week. There you can also find the best cheese shop in the world, Laurent Dubois, and next door is a wine shop, so you can get all you need for a nice afternoon at the Balcon Francais in the apartment.
We tried some of the recommendations from Stéphanie and they were all really good.
Most of the nights we had dinner at restaurants in other districts in the city. It was easy and comfortable to go there with Uber. In 2-3 minutes you had the car outside on the street.
I can also recommend a morning jog along the Seine. You will meet some people with dogs and some other early morning joggers and get some fresh, morning air to start the day.
The apartment is light, has large windows and is quiet thanks to the location on the highest floor of the building.
The bedroom has a lot of storage for your clothes and stuff and a large bed that's really comfortable. We slept very well.
The sofa bed in the living room is also comfortable and easy to unfold, but might be a bit short for a tall person. Perfect for kids and teenagers though.
The apartment was very clean and functional. We didn't make any dinners in the kitchen, only preparing breakfast, but you should have everything you need there.
The guys from the checkin company that met us and also did the inspection before departure were professional and easy going. We didn't meet Stéphanie, but had a lot of email communication and always got answers fast and clear in a very friendly way.
We have had a splendid four-day visit in Paris and hope to come back soon.
