We stayed for 2 nights at Christine´s place, and could not be happier. There is enough space for 2 people, and it is lovely furnished. The balcony is a big plus, and even the bathroom is big for Paris. You can reach the apartment via lift, which is very comfortable, and not that common in Paris. The communication with Christine was so easy and she replied quickly. The apartment is located near the lovely parc Butte Chaumont and you can walk easily within few minutes to many spots in Belleville. The metro is close by. We can only recommend this place.
