We had a really pleasant stay at Carole's studio. It's a cute and cosy little place, just right for a couple planning on a short stay (like we did for about a month). Located right at the 6th arrondisement, just a short walk from the Jardin du Luxembourg, Gare Montparnasse, Rue du Bac (where the ever so famous Bon Marche is located), one couldn't really ask for a better area. One of the biggest advantages of place is the metro connectivity, having 3 metro lines - 4, 10 and 12, accessible from 3 different stations - St.Placide, Rennes and Sevres Babylone all of which are within 400m of the studio.
Small as it may be, the studio is equipped with all the requisite paraphernalia for a comfortable stay - kitchenware, fridge, microwave, additional sheets, duvets, towels, cleaners - the works. The only possible 'luxury' missing out would be a television (but hey we're in Paris, why spoil the experience with the box).
Carole was a very gracious host who was always available in person or over the phone to provide us any assistance or support when needed. Though she speaks French mostly, it really didn't come in the way of our communication (it did help that my wife and I could speak a gentle bit of French ourselves). We had a small wifi issue, caused by a delayed response of the service provider but Carole and her family went out of the way to resolve it for us, even volunteering to buy us a new internet 4G dongle, but thankfully the problem was fixed.
I would recommend this place to anyone for all the above reasons. Set your expectations right, and you could totally enjoy your stay here.
