We stayed at the apartment for four nights. We were looking for a relaxing place to stay, slightly away from the very centre of the city, but near enough to it so we could get around by foot and not too far from the Gare du Nord. We also wanted to be in a neighbourhood so we could live like locals and explore parts of the city we hadn't visited before. This location was perfect for that, just by Oberkampf and Marais, near lots of really great restaurants and bars. Nothing too lively though, so if you're worried about noise, there's nothing to be concerned about. There's a great bakery just down the street, and a good supermarket almost directly opposite.
The flat itself is on the second floor of a lovely apartment block, so away from street noise. The bed was super comfortable, the kitchen was well equipped and the shower was good. The flat was also very clean and tidy, and cosy too. We wouldn't hesitate to book another stay in the apartment, we had a great time.
