I spent a wonderful time staying in Justine's flat! Justine was the best host I've had, I felt like I was visiting a lifelong friend. She was kind enough to invite me out with her friends to welcome me to the city, and we all got along nicely. Her apartment is on the 7th floor (8th floor American) without an elevator, but the view from the balcony is spectacular and I loved spending time out on the terrace. You'll be staying in Justine's living room, which has a door for privacy at night, but it's more of a shared space during the day. Nonetheless, the room is very cozy and inviting. The kitchen, although small, has everything you need to make simple meals if you're on a budget. The apartment is near a metro station on line 5, and you're one block from the trendy Bassin de la Villette. Also within walking distance in the 19th are the Parc de la Villette and the Parc des Buttes Chaumont, both are must sees. I fell in love with the quarter because it's away from the tourist crowds while still having the feel of a busy Parisian neighborhood. I hope to return again!
