The apartment is a real jewel in Paris, especially if you consider the price.
It is really hard to find awesome places like this in the city, for this reason I highly recommend this listing.
The apartment has everything for a solo travelers or a couple (maybe quite for young, beacause to save room, the have a mezzanine bed, which I find a quite smart idea!). Bathroom is new and the shower is fantastic!
The location is not very central, but very close to the subway, so no big deal. And honestly I'd rather stay in such an apartment rather than be totally in the center and be in a crappy one ;-)
