For me it's a perfect place to stay in Paris. Metro and bus within 3 minutes walk, room is small but with everything I need. I tried Banette, the local bakery opened at 7am; Des gâteaux et du pain, the famous female chef made excellent cake and bread; Le 41 Pasteur, the french restaurant provided great food and dessert, dinner costs around 30-50 euros; Les jardins de Shah Jahan with decent indian food. You can wash cloth at Laverie libre-service(bis, 1 Rue Brown-Séquard), buy farmer produce to taste and cook at a shop on Rue Falguière. All within 5 minutes walk.
Walk further, say 15 minutes or more, there is a huge MONOPRIX(31 Rue du Départ, 75014 Paris), a crepe street (I tried Crêperie Chez Jeanne at 58 Rue du Montparnasse and it's lovely), Lafayette Montparnasse Galleries with less people, FNAC with LPs, CDs and books.
On Saturday there is a farmer market Marché Saxe-Breteuil within 15 minutes walk, opened from morning to noon. Everything is fresh, you can find cheese, vegetables, meat, seafood and roast chicken.
If I had chance go to Paris again, I'll definitely book Jacques' place three months in advance -- it's popular! Thank you Jacques.
