Most Greek hotels are mediocre unless you spend over $500 a night. Against North American or Asian standards, deduct two stars.
Pros- helpful staff, ideal location close to everything, safe area with many restaurants, and right next to the subway station. They off source breakfast to a nearby restaurant with a 5 selection limited menu which was very good. This location also serves far more elaborate breakfast which might be worth exploring.
Con’s: small, cramped and basic but clean.
