Ok as a Hostel
The Hostel style rooms with bunks are good, although the top bunk seems a little unstable. No socializing area. Breakfast was good, location very central (bit dodgy at night but I never felt unsecure).
With a stay at Cosmopolit Athens Hotel, you'll be centrally located in Athens, steps from Omonia Square and 11 minutes by foot from National Archaeological Museum of Athens. Featured amenities include complimentary wired Internet access, a 24-hour front desk, and luggage storage. A roundtrip airport shuttle is available for a surcharge.
