Absolutely nothing.
Papillons do not need to go to get clipped and groomed by a groomer. Their hair-coat is easy to maintain by brushing a couple of times per week, with emphasis under/ around ears, and hocks (hind legs).
Papillons adopt easily to a variety of life styles, learn well, are trained easy, but , like most dogs, or other house pets, cherish a regulated household, with regular routines.
