I stayed at this apartment for the month of June in 2022 to kick off nine weeks of traveling. I had stayed in Le Marais years ago and wanted to return. The apartment is in a perfect location, close to the Metro, some main arteries of the Right Bank (north of the Seine), and tons of great restaurants, coffee shops, and bars, not to mention walking/biking/transit distance to pretty much anything you would want to do in Paris. What I found best is that the street it sits on actually becomes much quieter as a block further south it closes to traffic. Almost every night I slept with the windows open because of the hot days and, while not completely quiet (it is in the heart of Paris after all), and being on a "quiet" block helped a lot.
It's also worth noting that I stayed here while working remotely. I had no issues with the internet, whatsoever, even over video calls. I used the larger bedroom as a dedicated office because it has a desk and slept in the smaller ones with the larger closet. The kitchen has everything I needed to make simple meals when I wanted to eat in and the bathroom was much more spacious than expected. The beds were simple but comfortable enough for me.
Also, a final little note, Anthony was an excellent host. He brought an extra fan when I arrived as I had a hunch it was going to get hot. He ran back and forth a few times to make sure we had what we needed and was always incredibly responsive for anything we needed, not to mention generally personable and friendly.
Thanks for a great stay, Anthony! Hopefully I'll be back soon!
