The hosts are friendly and enthusiastic. They helped us every morning with our travel plan and gave us useful information. Our room is cosy and comfortable. In addition it is filled with all kind of books from tour guiding to comics. ( There is the largest amount of Tintin series I have ever seen :O) You can go to Opera within 15 min walk and Louvre is also not far from the place. The transportation around is also very convenient and only a few minutes walking distance to bus stops and metro stations. Every morning they prepared delicious breakfast in time, and croissant is my favorite of all.
Highly recommended!!!!
