I don't know how to explain just how pleased I was with Gaspar's place: I couldn't have designed a more ideal Paris apartment for our stay if I had tried (well, the five flight walkup was maybe not ideal with a whole summer's worth of luggage, but the workout was good for us, and the accommodations were absolutely worth the effort). The reviews already posted do a good job of identifying its principal charms (appealing shabby chic / boho decor, attractive but edgy neighborhood that's not seething with other tourists, comfortable space for 3-4 people, excellent view). What I liked, especially, was that it seemed to me (based on limited information) to be an authentic Parisian flat, occupied (when not being rented) by a local who, although he didn't spell out directions to the local hotspots, captured the essence of the place with his choices. Can you believe we only got to stay there for one night? Anyway, my husband and I were with our small son (age 6), who found the apartment just as magical as we did. If it's available, and your taste runs toward places with character rather than sterility and convenience, go for it. I've stayed in many forgettable Airbnbs, but I won't forget this one.
p.s. The mattress is firm. This came as a huge relief to us (we live in Asia, where mattresses are firm as a rule, and had just come off of six weeks on revoltingly soft American beds), but if you're picky and like those pillow top atrocities, you might wake up grumpy.
