Hello Mandy,
Is this a private "Harrison" topic or can anyone join in?
I'm sure you are right, it is Ierapetra. Some people think the initial "I" is an "L" and call it Lerapetra. I heard a native pronounce it and it came out as Eer Rap Etra, with the emphasis on the "Rap".
It's on the south coast (east) and I visited in the 80's when staying at Ferma, just to the east. Nothing special I seem to remember.
By the way, on your extensive travels have you and Chris been to Makrigialos (also spelt Makriyalos) or Myrtos which are east and west of Ierapetra respectively. They both seem to be featured by Kosmar.
