First of all, Sophie was an incredible host, not the best you can have, the best you can imagine. She was kind and accommodating, flexible with check in and check out times and always avaiable for any questions I could have. I was greated by her with a box of delicious french pastries and a fridge filled with all the escencials for a great breakfast or brunch, and toured through the apartment while she made sure I understood how everything worked. She also left a folder with useful information like restaurants and contact numbers.
Second, the location. For me, there is no better location to stay in Paris. Near Notre Dame and the Hotel De Ville you are surrounded by restaurants, shops and cafes. Geographically central, you can practicly walk to anywhere you want.
Third, the space, spacious and well decorated, with a beautifull view over de Seine that makes it hard to leave the apartment.
Overall, I can not imagine a better place to stay in Paris.
