Yes, convenient and quiet, and I would also add great location (very good metro connections), clean, perfect for 1-2 persons (can squeeze in 3 if you're good friends). There's a reasonably priced supermarket just 20 m from the apartment, safe neighborhood, 10 minutes walk to Moulin Rouge, 20 minutes walk to Sacre Coeur. If you take Place de Clichy metro (5-7 minutes walk) you have direct connection to La Chapelle - Gare du Nord, take the train from there and you're in 45 minutes to Charles de Gaulle Airport (even in snowy weather).
Gerald is a great host, it's easy to reach him and he gives quick feedback. Had a most pleasant stay at his apartment.
