Other things to note Also we don't provide olive oil. We can also provide you with a safe and secure storage space for your luggage if needed via our business partners office at Koukaki, near Acropolis. There are two different locker sizes (medium and large) with the cost being 5 and 6 euros accordingly. The cost is per day and for more information feel free to reach out to us :) Lastly, check-ins are available between 14:00 and 23:00. For arrivals after 23:00, there is an additional €20 late check-in fee, which must be paid in cash to the staff member on duty. Registration Details 00000595390
