A really good location within short walking distances to outstanding patisseries (e.g. Le Petit Parsien and Du Pain et des Idées), excellent and reasonably priced restaurants (e.g. Pramil, Le Parisien, Au Basco, Pizza Populare) museums (Picasso and Pompidou to name two), several Metro stations, and all of the necessary conveniences like food markets, banks, pharmacies, and convenience stores.
Claude communicated well and our trip went off without a hitch. We were comfortable during our trip and, as expected, we didn't spend a lot of time in the apartment. A few highlights were the fantastic tips on where to eat (best food trip ever!), amazing location, peaceful environment, and the electric water heater, French coffee press and coffee! The washer and dryer was also nice and came in handy.
Note that there is one flight of stairs to climb that curves a bit at the top. It was easy enough to navigate but don't rush. Also, the stairwell has light switches at the top and bottom of the stairs which are a must at night.
