Pros: The contact from Guillaume was great and extremely helpful throughout our stay. The apartment is quirky, clean and not too far to get around Paris.
Cons: unfortunately it was extremely loud at night with neighbours playing music and shouting until late. The bedroom was very claustrophobic so we slept in the living room, it is a lot smaller than the photo makes out but this is just how we felt.
On the whole it was a great stay, very enjoyable and Guillaume is a great host.
