David's place is spacious, clean and in a VERY lively/multi-ethnic neighborhood. However, there's no noise from the street once you're in the apartment (located in a courtyard) which we really enjoyed as we were looking for a quiet pied-a-terre in Paris.
Note for families: no microwave and small fridge (no freezer).

Huge library of books for book lovers. Plenty of places to sit and relax.
About 10 minutes walk to Place de la Republique. Few playgrounds nearby (a good one close to the Monoprix in a back street). Rotisseries and patisseries abound on the street. Metro Belleville a few steps away. Only thing to note: We didn't feel like the neighborhood was very safe once the stores were closed for the night. Something you might consider if you're travelling alone with children.

Overall, I highly recommend David's place and we hope to return in the future.
