Here’s what Wikipedians say about Cirebon:

Although sur­rounded by Sundanese-speaking areas in West Java, lin­guists have stated clearly that Cirebon (and the his­tor­i­cally related region of Serang city in Banten Province) are Javanese lan­guage areas. In addi­tion, this is sup­ported by the Cirebon peo­ple refer­ring to them­selves as “wong Jawa” (“Javanese peo­ple”), and to their lan­guage as “basa Jawa” (“Javanese”). However, the Cirebon dialect is suf­fi­ciently dif­fer­ent from the dom­i­nant south cen­tral Javanese dialect that it is some­times assumed to be non-Javanese by outsiders.

What I can tell you firsthand:

• It’s a nice coastal city around Java. People are friendly and the city is clean.
• Ancient peo­ple believe that it was the cen­ter of the uni­verse (the name Cirebon, derived from such notion).
• The city is one large nat­ural sym­phony, try rid­ing one of its tri­cy­cle and you’ll see what I mean.
• It’s the only place where peo­ple com­monly speak two major, often con­flict­ing Indonesian dialects — Javanese & Sundanese, whom most peo­ple speak either of them, not both.
• It’s a coastal city, so it’s warm all year long. 10 km up, lies a smaller city of Kuningan, down the hills of the Mt. Ciremai, It has one of the world’s best nat­ural spring spas & swim­ming pools.
• Due to its warm weather and hot sunny day, nap­ping is a com­mon cul­ture dur­ing the day.
• It offers Nasi Jamblang, a com­mon mixed-rice dish served on top of teak tree leaves.
