Great location. Close to everything you need (e.g., grocery store, restaurants, shops). We walked to the Louvre and most of the main attractions. The Apartment is as described and shown in the pictures. It's very small when the couch is folded out but you don't need much space when you sleep anyways. There is a small kitchenette which has most essentials. We ate breakfast in every morning.
Down side is there is no door to the bathroom which is a bit uncomfortable. The shower is also very small. Toilet requires a few flushes. These are just minor things and were no deal breakers for us. The place is in a great location which mattered the most to us and Justin was super helpful and flexible with our stay. He always responded right away. Would stay there again!
