5 stars for the location. restaurants, bars, boulangeries and groceries are about a block away. metro stops are within a 10 minute walk.
we rented both units for 6 people. the space is not large but comfortably fit all of us. the units are in separate courtyards and connected by a short set of stairs. travel time between both = about 15 seconds (according to my 7-year old). the nespresso machine was a bonus.
be careful not to lock yourself out. there are signs posted in both units saying don't leave the keys in the doors. the signs should also say always bring your keys with you or leave them in the lock boxes. the doors to both auto-lock and can't be opened from the outside without keys. the locksmith cost for us was 150 euros.
