You are staying in Hemmingway's Paris with Jean-Marc's home. It is a deeply personal home, filled with authentic treasures- all well displayed. It looks, feels, and smells of a person who has traveled to exotic lands and has brought back a piece of each his travels. Every nook and cranny is charmingly carries an original piece- whether that be statue, art, talisman, etc. Jean Marc is clearly a collector of many things, one of those being books. This apartment acts as his personal library. We stayed for 6 days and I still did not find time to browse all of the selections that were available to see. It is like walking into a fine French book store.
The apartment also has style. For example, the pots are all heavy grade copper. The bath is so large it is almost a mini-jacuzzi and it sits in privacy with large plants all around giving you the feel like you are bathing in a jungle. There are elements of China, Africa, Brazil, Central America, Russian throughout. It is of course exuding Paris France as well.
As an American, some things to note. As Americans we are used to AirBnbs that are stripped down to a coffee machine and not much more. Here, as you walk into the apartment, there is a scent of old books and fine tobacco, and good food. As in most apartments in France, there is no AC, fans are used, and there are two large ones which work just fine (the temperature falls down to the high 60s at night). The apartment is dashingly organized by blind shades for privacy for each loft as well as the tub area, and there is visual privacy but not the noise privacy from room to room that we- as Americans- are used to. These are things that are French, and this is why we travel to France. To experience living in a different way- the French way- if even for a week. Embrace them; they are not drawbacks.
In terms of location, the apartment is in located in the epi-center of the coolest, hippest district in France: the Canal Saint Martin. It is incredibly accessible to every arrondissement by metro, foot, uber, bike, and or scooter. (I highly recommend Lime scootering Paris.)
Overall...
I travel often for work. This is by far one of the Top 3 coolest places I have ever stayed.
Highly recommended.
