"We chose Mediation to organize an eco-themed urban scavenger hunt in Luxembourg for our team-building event, and it was a huge success! Everything was quick and easy to set up; they’re incredibly approachable and flexible—it was a real pleasure to organize this with them. The scavenger hunt itself was fantastic: we had a great laugh, learned a lot about ecology and our city/country, and most importantly, had a wonderful time together. In short, if you’re looking for a fun, well-planned, and hassle-free activity to bring your team together, go for it!"

"We had worked with Mediation in the past, and it had been a success. When we took on the KlimaExpo project, it was only natural that we turned to them. Once again, they proved themselves to be highly reliable. Despite very tight deadlines and the complexity of the project, they managed to make this first edition a real success. Thank you to the entire team for this excellent collaboration!"

Finally, we received a number of very positive comments from our guests."
