I had an amazing time at the apartment. In a very hip part of Marais that isn't completely touristy and a just a few mins walk from the Picasso museum and the heart of Marais. There's a bunch of great coffee shops, boutiques and a record store. It's also right around the corner from the 8 train and a super market. Looks exactly like the pictures and I would recommend this apartment to anyone.
Arianne was very easy to communicate with and provided a written list of places to eat and check out. She also emailed me helpful directions from the airport. She was very responsive and a great host.
