Wonderful place to stay. We were a family of 5 adults and 4 children and the house was perfect for us. Plenty of space in the house and big rooms for everyone. The room downstairs was cold despite it was very hot in Paris, and we really used it to play with the children.
Apart from that the location of the apartment is just perfect. Sant Martin area is one of those places you would love to live if you settle in Paris. A lot of people around, and a bunch of nice restaurants and cafes. And the canal itself is a perfect place to sit and enjoy the sundown. Also, the distance is “walkable” for many of the main tourist areas like the opera, notre Dame or the Louvre.
In summary, perfect place for a big group of friends or family.
