Mathieu's place was perfect for us on our first visit to Paris. The apartment is admittedly tiny, but also charming. Probably not for those who want space and luxury, but to us it felt like the kind of cosy hideout where you might retreat if you were reckless young lovers (which we are far from being by the way). The location was incredibly convenient for getting to anywhere we wanted to go, and the local shops, cafes, brasseries and restaurants seem universally excellent. Just watch your head if you're tall. Although we didn't meet Mathieu in person, communication was good and we had no difficulties.
