Writing this on behalf of my parents who I'd booked Liu's apartment for, as a surprise trip to Paris. They had a great time in the apartment, and said the location was amazing, and such a beautiful historic street.
I liaised with Guillemette (Liu's children's nanny) right up until the day my parents arrived and she was very helpful and responsive. They apartment was clean and quiet, just what they needed for a one night stay in Paris.
