Board member of the Lecturers without borders Mikhail Khotyakov who is teaching mathematics in German schools shares one of his lectures for high school students starting from grade 7 or 8 about countable sets in a Hilbert Hotel example. Mikhail calls it a Naum Vilenkin Hotel, since he first learned this concept from a great popular science writer Naum Vilenkin. The latter also developed and beautified the concept.
