We track 343 hotels in Greece, 343 of which have had a research pass. Across the 31 with a coffee setup on record, the most common in-room system is the capsule machine.
Mains supply here is 230V at 50Hz, using plug types C, F.
A plug adapter changes the shape of the pins and nothing else. A single-voltage kettle from a 120V country will not work safely on a 230V supply no matter which adapter you use — check the label on the appliance for a dual-voltage range before you pack it. More on travel kettles and voltage →
