40 Rue de Gravilliers is spot on from a location perspective.
apartment is smaller than expected, yet functional.
communication was great, however we were not personally met or checked in, but rather sent on treasure hunt to search and collect the key 200m from the apartment, of which we were only advised of last minute. it was confusing and cumbersome
sadly we were there during a heat wave, and the one small, dirty van made so much noise, so did not sleep well.
recommendations with regards to food shopping, local markets, restaurants, travel apps, Metro info or a Paris map would have been very handy and very welcome
