Although the room wasn't equipped with the following, I was given them on request:
Extra pillow
Hot water kettle - there are no coffee fixings in the room, but a coffee shop immediately across the street.
Also, like every hotel I stayed at in Greece the mattress was very hard. I like a firm mattress, but they all made my shoulders and hips sore, leading to a more restless night. I'm 5'10", 180 lbs, so an average guy.
The staff was very friendly and helpful.
