Noisy, very hot, highly bureaucratic and extraordinarily expensive. To access power just for one night you are forced to buy a card for 10euros which you cannot return or use anywhere else, and this is even before you pay for the actual power. 40minutes and a mountain of paperwork just to stay one night. The included internet is almost impossible to use and the office staff just shrug and blame their Istanbul office. Expect strobe lighting and club music most of the night, it's impossible to sleep. Never again!
