I just spent five great days at the apartment and can highly recommend it. It's a short walk from the Jacques Bonsergent metro station (orange 5) and right next to the canal. It's set back from the street in a courtyard so is very quiet and there are some great cafe's and bars nearby as well as a Carrefour.
The lift must be the smallest in Paris but it's only 3 floors if you're claustrophobic! The apartment comes with all the amenities you need (although I couldn't work out how to use the hob), the shower is lovely and the bed is very comfortable.
It's a really nice area and the apartment is perfectly situated to easily get around the city.
