Fantastic stay - easy and convenient check-in, the check in person even carried my bag up to the flat. The bed is very comfortable, plenty of towels, fully stocked kitchen, everything was great and as advertised. I used the washer/dryer, worked perfectly. The apartment is on the third floor (called second floor in France). The location is amazing - in the heart of the Marais, close to several metro stations, plenty of shops, grocery, restaurants, etc. close by.
My only note is that the apartment faces the street so there is some street noise.
I would absolutely stay here again! Highly recommend, great apartment for the price.
