We loved Buttes Bergeyre, a really great neighbourhood, full of friendly people, dogs and locals. Near Buttes Chamont which is a super park, the canals, Belville and within reach of central Paris.
It was pretty hot when we were there so the ground-floor apartment and large terrace worked really well for us. Plenty of space for two, one of us worked from there. The apartment meets all your basic needs and has more space than most Parisian homes.
