The 7th arrondissement is the priority for Florence, especially somewhere near the Ecole Militaire, a neighbourhood she is particularly fond of, which is relatively near her work.
The apartment has to be about 50m2 (538ft2), so that she can live alone and enjoy enough space. In addition to the neighbourhood, she wants a large living room and good storage space. Quiet surroundings are not important because she is used to the noise of the city. Luckily for her because she does not want an apartment with a view of a courtyard!
