Magali's apartment was perfect for me as a solo traveler. It's close to both the metro and a supermarket, as well as numerous food and drink venues. Would recommend Paname Brewing Company around the corner for a beer on the waterfront if you get some nice weather.
It's also extremely easy to get to the apartment if you are travelling from Gare du Nord - either a 30 minute walk or a short direct metro ride.
The apartment is well equipped with all the necessities, including a small stove and kettle.
The courtyard cats were an added bonus and I Ioved saying hello to them when I would leave or come back; they were all very friendly! The (human) neighbors are also very nice, and the space felt safe.
I would definitely stay here again when visiting Paris :)
