My boyfriend and I visited Paris for 9days and we stayed at Marine's apartment. It was our first Airbnb experience. And it was great! Communications, directions and handling of keys were all made easy by Marine. Though she wasn't in town but had her sweet friend Marina to handle communications.
She even provided guidebooks and a hairdryer for me upon my request, even when it was not stated in the amenities.
Apartment is nice as in photos and location is fantastic, good wifi reception, close to a number of Metro stations and also walking distance to Bastille market and shopping streets in Le Marais district. Only thing was, it got rather warm for a couple of nights during our time in Paris. Summer temperature in Paris can get a little fickle. But all in all, it's a great way to experience Paris living in the very lovely neighbourhood of Marine's apartment. Highly recommended.
