I had the opportunity to work with Calliope when I was organising a convention for 900 people at the Cirque d’Hiver in Paris. First, communication with my Calliope representative was excellent in the run-up to the event. Then, on the day itself, it was very pleasant to work with the interpreters, who were there to interpret a two-hour plenary session. I have absolutely no hesitation in recommending Calliope!
