Maud's studio is one of the coziest and most beautiful apartments I've ever seen. It may be a little bit small, but it has everything two people on vacation may need, nothing less and nothing more. (Also, her taste in forniture is absolutely great).
It's easy to reach from the closest metro station, and it's in an absolutely great area of Paris: full of bars, little restaurants and, most of all, cheap 24h mini markets (if you're thirsty or hungry at midnight, they sure as heck have what you need). Although we didn't have the chance to meet Maud, she's been able to make us feel comfortable and at home. Such a nice host and apartment :)
