Justine's apartment is lovely, full of character and very welcoming, exactly as per the photo's and as described in the listing. (The stairs are a bit of a struggle after a long day walking around Paris but manageable and well worth it for the views and enjoying a drink on the roof terrace). Justine met us on arrival showing us around the apartment and giving us recommendations for places to eat etc. Justine was very friendly, helpful and flexible with regards to our check out time. Very easy to contact via the Airbnb messenger with quick responses to any questions.
The apartment itself is in an excellent location within a couple of minutes walk to the nearest supermarket. The nearest metro is at the top of the road and it's within an easy 15 minute walk to the Louvre and Pompidou Centre. There is a pedestrianised area of shops and restaurants within a 5-10 minute walk also. If you are arriving via CDG airport it costs the same to get a taxi/uber as it does to get the train and tube (approx EU 60).
We thoroughly enjoyed our stay and would not hesitate to recommend this apartment to anyone.
