The hotel is a walking distance (15-45 min. away) from all major points of interest, and a few steps away from Omonia metro station. My room (601) was clean, comfortable, and quiet. The breakfast included was tasty and plentiful. The staff was friendly, polite and professional.
Overall, the hotel is probably the best value-proposition in the Omonia area, and an excellent accommodation choice when in Athens. Highly recommended.
