Had a great 3 nights stay at Antonella's place. The room is exactly like in the pictures. There are two bathrooms in the house, one next to the room and the other one at the floor below (only this second one has a toilet). I definitely recommend this for someone who wants to enjoy Paris by foot (the location is exceptional!) and at a reasonable price.
Also, Antonella was very understanding about leaving my luggage at her place after check-out and bringing the key later.
