Olivier's place is amazing. It is 6 floors up with a beautiful view up and down the Rue de Thann, 30 seconds walk to Parc Monceau and very close to two metro stations. Just on the other side of the park is a grocery store and the entire area is beautiful and easygoing.
Things to be aware of:
- there is no AC, which was hard in the summer (I got very hot during the heat wave)
- the sink and shower are old and can start to malfunction if you aren't careful to take care of them
- the toilet is not a sitting toilet, as you can see in picture 5
- there are 100+ stairs up to the apartment, so if you don't like the idea of walking up and down those every day then keep that in mind
As long as you know what to expect, I would happily recommend Olivier's apartment to anyone who wants to spend several weeks or several months in Paris.
