We (myself and 3 adult kids) stayed at Brooke and Pierre's place and found it to be the perfect space for us. There are two showers and one toilet. The two bedrooms and the pullout sofa bed enabled us to spread out. They have made good use of the space available. The location made it easy for us to walk around and/or take the underground. Shopping and restaurants are nearby.
Would definitely stay here again should we return to Paris.
