Electra Metropolis is a well known property, so I was expecting value for the higher tariffs. The service was a let down. We had 2 rooms , we checked in 10 pm, asked for late check out 1 pm next day - the check in person confirmed. Next morning we get a call saying please check out 11 am, hotel is fully booked, hotel policy, etc. Once a hotel reception staff during check in confirms, we would trust that the staff next day will follow through. But not the case at the Electra Metropolis. Breakfast venue has great view, but was quite crowded and getting proper service - getting coffee, but not the milk, not having salt and pepper etc. are not the kind of service you expect when you pay this much.
I suggest skip the Electra Metropolis, lots of other options with better service in Athens.
