Easily the best accommodation I have stayed at in Paris.
I lived in Paris for many years and I can honestly say that Marine's apartment has it all: well-located, beautifully-decorated, spacious, clean, fully-equipped and with a lightning-fast internet connection (we had to work a bit while we were there).
I love the 12th arrondissement, it is still a relatively non-touristic place compared e.g. to Le Marais, yet the metro station is only a few minutes away from the apartment and the bus stop is literally in front of the door, so you can easily get to anywhere in the city in a matter of minutes.
Marine was a great host, we never met but she left the keys for us in a nearby locker and the whole check-in procedure was flawless, there was no waiting around which was perfect since it was pouring rain when we arrived.
She left detailed instructions, a map, chocolate and even a bottle of wine for us in the apartment. She checked by phone that everything was ok and responded very quickly to the couple of questions we had in the following days.
It was a wonderful experience and we are very much looking forward to staying at her place again on our next trip to Paris.
