If we ever make it back to Paris I would gladly stay here again. The apartment is in a two minute walking distance to a metro station and there are many restaurants and shops in the area. Gaspard was very hospitable and even let us check in early due to our flight arrival. He also was extremely quick to respond when we had a couple questions. The neighborhood is very safe, almost every night we walked to dinner fairly late ( around ten) and came back close to midnight and never felt unsafe.
The apartment itself is pretty small, however if you are not planning on being there much of the day that shouldn't matter. The bathroom was my favorite part of the apartment because it was so big and has not just a beautiful shower but a bear claw tub which I was only able to use once to my regret. Gaspard also has a house keeper who will being fresh towels and sick while your gone. She even did the dirty laundry we had. Overall I was very impressed. The only thing which could be confusing is that the main doors to get in, just get you into the courtyard. Then there's the doors to the building and once in the door to the apartment. Gaspard does explain that when he sends check in instructions though.
