Nice and clean apartment and very friendly hosts. A bit noisy because of the restaurant below and the neighbours, but we didn't mind too much and had earplugs with us.
The apartment is in a nice area and there are lots of nice restaurants, bars and shops on walking distance. The metro is right in front of the house, but if you have to pick up the keys first you better get off at Rue Saint Maur. And another tip from us: if you come by car, you can park at Galieni, then take the metro for a few stops. Book in advance and it'll cost you only 20 € or so. It takes 10 minutes to get to the apartment.
