We booked the flat for our family for the Easter weekend. We live on the same street so we know the neighborhood pretty swell. It was quite convenient for the flats to be close by so we could organise dinner at ours. François was easy to communicate with. The checking in and out were both pretty smooth. Abbesses is a lovely neighborhood. There are lots of things to do around (great places for brunch, nice restaurant and a jazz club - sacré cœur, the artists' place) and south Pigalle is not too far if you feel like going out. I would therefore highly recommend staying there.
