Apartment - "Charming Apartment with a Terrace" is a light-filled, comfortable place suitable for a couple. It is on the top floor of a newish building, on a quiet neighborhood street just off lively Rue des Pyrénées, a few blocks from Pl. Gambetta. The apartment is filled with books and collected items that obviously have sentimental value for the owner(s). Terrific water pressure in the shower, bathroom storage baskets for toiletries, lots of kitchen small appliances, excellent WiFi, very comfortable bed, and generous space in the dresser; closet space was a real challenge, however. Since the apartment is occupied by the owner(s), supplies were idiosyncratic -- as one would expect, lots of one thing, nothing of another. Sadly, the weather was unseasonably cold the week we were in town, and we could not use the terrace. Still, it was nice to have it there.
Neighborhood - one of those quintessential areas that make Paris so self-contained and pleasant to visit -- lots of excellent gourmet shops (cheese, meat, bread/pastry, meat, chocolate, produce), druggists, dry cleaners, florists, grocery stores, and restaurants (many ethnic). Unfortunately, we were not able to meet Françoise, but her friend Natacha met us with the key. Natacha knew of only one restaurant in the neighborhood -- Aux petits oignons, 11 Rue Dupont de L'Eure. It was very good, but everything else in the area was rather pedestrian and over-priced. We would have appreciated a list of favorite restaurants, gourmet shops, or local events from the owner -- one of the perks of renting from someone who lives in and knows the territory.
Location - If this is your first (or second) visit to Paris, the location might not serve your needs well. Metro transportation (line #3) is not particularly efficient - particularly now that the transfer to line #4 is disabled at Réamur Sébastopol. However, many bus lines cross Gambetta so it would pay dividends to study the Paris bus map (in advance, if possible). The buses are well organized and run frequently. They just take a long time to cross town. Plan on at least an hour getting to the center (or more beyond). It comes down to factors of cost -- time (plan on at least an hour getting to the center of town), and money (ten pack tickets = 14.90€).
Itinerary Disadvantage - only one set of keys eliminates independent travel, particularly inconvenient over a longer stay (ours was for six nights). Although we had different goals, my husband and I had to compromise to such an extent that we could not visit all of the exhibits on our individual lists. Other than to the market, we were forced to visit the same museums at the same time. A second set of keys is essential for longer stays.
