My family and I (4 people, including 11 and 13 year old children) spent just over a week in Sophie's flat. It was a last-minute booking due to the cancellation of our reservation by a different owner. Sophie was quick to reply with answers to my questions. (Which was very helpful, since we were leaving the next day for the first leg of our vacation.) The apartment is the penthouse of a six storey building (lots of stairs if you would like a workout), but there is an elevator that fits three people at a time which goes to the fifth floor. Sophie's husband, Diego, met us at the apartment and explained everything. The apartment itself is nice and comfortable. There are three bedrooms - one with bunk beds and two with double beds. Our daughter claimed the bedroom with a view of the Eiffel Tower, and she enjoyed watching it sparkle every hour after dark. There is one bathroom with bathtub and separate shower (which everyone agreed was wonderful!), and a toilet in its own room down the hall. The kitchen has everything we needed (although we couldn't find a baking sheet) and a nice big island with stools to eat at. The living room has a sofa and three other chairs, so there is plenty of comfortable seating. The living room, kitchen and two bedrooms look out over the gardens at the Musée du quai Branly. The location of the apartment is fantastic! It was delightful to see the Eiffel Tower when leaving or arriving home after a busy day. The RER is handy, the Metro is not far, and there are several bus stops nearby. (We took the 42 from Gare du Nord - Sophie's suggestion, which which was very easy - after taking the Eurostar from London, and were dropped off right around the corner.) We had a great time in Paris, and Sophie's apartment was a big part of it.
