Diane's apartment is perfectly located. Very close to Goncourt metro station from where you can reach a city centre in less than 15 minutes. The neighbourhood is also very interesting and full of cafes and restaurants (We truly enjoyed the Canal Saint-Martin area)
There is no lift in the block and the apartment is on the 5th floor but the view from the balcony compensates the efforts. The flat itself is very nice, comfy and well equipped. It seems that someone genuinely lives there not just rents it for the touristic purposes. Therefore, it makes it truly authentic and you feel really welcome there.
Diane is keen to help and responds for the messages very quickly.
I would definitely recommend anyone planning a trip to Paris to stay here :)
