Marie's apartment in Le Marais was fantastic. The area is close enough to everything so you can walk everywhere. We spent the entire weekend walking around the whole city and clicked up some miles on my fitbit!
The apartment is exactly how I'd image a Parisian apartment to look, very chic, lots of quirky decor and beautiful French windows. There's a lovely little bar on the corner of the street just a minute walk from the apartment too.
Marie was also kind enough to let us leave our luggage in the apartment for the day after we checked out so that we didn't have to find somewhere to pay to leave them. Which was very helpful of her.
All in all a great trip and I will definitely be back again soon :)
