We stayed as a family with 3 generations. The apartment is located in a very central area and short walk to the Louvre. It is very quiet for car traffic, however plenty of pedestrian activity to keep you interested. Supermarket and many restaurants and cafes very close by (ie down the lift and out on the street). We felt very safe here - no yellow jackets in this area. The photos were true to reality as others have mentioned. We did not experience any noise issues from the juice bar as some others have indicated in other reviews - we stayed 4 nights including a weekend. It is a very quiet area and the bedrooms are towards the back of the apartment - sleeping was easy. One electric toilet and one normal toilet - you should not worry about the toilet comments made by others. Very good hot water.
The apartment is very spacious and the kitchen was very excellent. Plenty of utensils, plates, etc. The washing machine also a welcome addition. We can't fault this apartment or location at all. I would certainly rebook and would recommend to anyone, either single or family as the peace and quiet that you get here is very much valued when in a busy city like Paris.
