Contact the Mobilier National in advance either by phone: 01 40 13 46 46 or by email:
reservation.publics @ rmn.fr and they will arrange for an English-speaking guide.
The tour is officially only by “fonctionnaires” (government employees).
You can make arrangements to have a translator along with you on the normally scheduled French tour (Tuesday, Wednesday, Thursday) at 1:30 p.m. Notify them that you will be bringing someone along as a translator and the guide will speak slower.
Or you can come along on the regular French tour and listen in French and have a copy of my guide with you.
Eve Lambrecht (contact numbers and address above) is the person to contact.
(I can recommend that you contact Pamela Grant at Paris Perspectives and ask if she would be able to help you with a tour.)
