I highly recommend Christelle's lovely apartment to everyone who's looking for a small, comfortable place that's just a few steps away from the Champs-Elysées, a metro station and bars with much lower prices than the ones in the Champs-Elysées itself. However, the drinks are just as good. All in all, we felt really safe in this area.
The description and pictures are absolutely true to what we found when we arrived. Everything was well organized. A lady named Estella was waiting for us in front of the building to guide us to the apartment itself and give us a few necessary information about it.
Actually, we didn't want to leave after our short stay.
We'll definitely be back one day! :)
