Dider was an awesome host. He speaks English very well. We were in Paris during protests that also led to some train/other disruptions. He gave us advice about navigating Paris in light of this as well as some cultural insight. His home is in a great location just a short walk from Gare du Nord and Gare de l'Est, the metro, and the bus. The apartment is clean, bright, and well-decorated. Highly recommended.
