Great location. Metro is only 4 minute walk, Notre Dame is only a 10 minute walk and the Louvre 20. Plenty of boulangerie's close by along with restaurants.
Check in is easy, apartment is clean and is as advertised. Good amenities available such as washer and dryer but be prepared to wait for the dryer as it takes a long time to dry a load of clothes.
Apartment building is quiet but there is street noise on a weekday morning but not as loud as some previous posters mentioned. All in all a really good value for the location. Mathilde was very responsive to our requests. During our stay we awoke early one morning to a hammer drill and construction/remodeling next door. Mathilde jumped on top of it and we had no issues afterwards.
A good rental.
