Firstly, Julien is an amazing host: available, provides excellent and timely communication, as well as very useful information and tips prior and during our stay. He was very nice to accommodate our late arrival, one morning brought us fresh croissants and chouquettes to try as a typical French breakfast and he even offered to drive us to the train station in case the metro was not running since we had a very early train (luckily the metro was running:)).
The apartment is super clean, has everything you may need for a nice stay. It is exactly the way you see it in photos. It is small, but has a separate bedroom (very comfortable bed) and kitchen (very well equipped with all basic amenities to prepare breakfast or light lunch). Since the apartment is on 10th floor, the view is beautiful and the neighbourhood is rather quiet.
Location is excellent, 3 minutes walking to the nearest metro stop, and the wider area is very lively with a lot of bars and restaurants. There are very nice bakery, excellent coffee place and cheese store all within 5 min walking. If you like walking and the weather is nice, you can even have a nice stroll to some of the sights.
Overall, it was a wonderful stay, I highly recommend it!
