Book an appointment for an appraisal
We welcome you without an appointment Monday to Friday, from 10am to 1pm and from 2pm to 6:30pm, at 43 rue Beaubourg (Paris 3ᵉ, Rambuteau metro). But if you prefer a guaranteed time slot — because you are coming from afar, have several pieces to appraise, or simply have little time — book your slot below. Reservation is possible at any time, including evenings and weekends.
The appointment lasts about thirty minutes, is free, and involves no obligation. You leave with a written estimate.
