Raphaël's apartment is absolutely super! We had a wonderful stay with a friend of mine. I love the area of Canal St Martin, there's plenty of bars and restaurants and Rebublique is just 5min away where metro connection to all around Paris is possible.
The apartment has great view and is very nice and comfortable.
The only challenge is the stairs, as in so many parisian apartments, when one is carrying luggage...
I would definitely stay again!
