Location: Appartment is very close to Arc de Triumph and Champs-Élysées. This is a very good location. But there are areas like Bastille and Marais which are even nicer for most tourists.
Appartment: Nicely furbished. For two people its fine. For 4 people its a bit crowded because the "sleeping room" is a tiny entrance hall. Once the bed is set up it is difficult to pass the bed and to reach the rest of the appartment.
Don´t expect a great view. Appartments in Paris tend to be small, this one is no exception.
Contact: Very friendly.
Summary: For Paris standarts it is a very nice appartment.
