We really enjoyed the month we stayed in Marielo's apartment. The apartment is south facing and is flooded with natural light that enters through floor-to-ceiling windows in the bedroom, study, and living-room. The kitchen has a skylight.
The appliances—fridge, stove, oven, washing machine, kettle and toaster—work perfectly. But, the best thing about this apartment is the fact it has a bathtub which, from our experience, is a rarity in Paris.
The apartment is located in the 10th arrondissement and is a five-minute walk to La Rue du Faubourg Saint-Denis which has many excellent cheese and wine shops, restaurants, bars, and eateries. It's a "must do" thing to buy a chicken wrap (sandwich poulet fermier) at least once at the Kurdish takeout on this street. Be patient because the line is often quite long and the meat is cooked on skewers on a grill right in front of you.
There are at least 3 grocery stores nearby—Franprix, Monoprix and Lidl. Lidl has the best prices, but for some reason manly French residents tend to shun this store, preferring to pay higher prices at Franprix and Monoprix.
There are 2 metros stations within a 5-minute walk—Chateau d'Eau and Strasbourg-Saint-Denis.
You won't be disappointed if you choose to stay at Marielo's. We loved it.
