Stayed for a night but it was a great stay. Room was spacious and clean. The staff was exceptional, especially Chris (?) who assisted with my check-in. If I hadn’t already booked my stay at another hotel months before, I would have stayed here for the whole of my trip in Athens.
Location is doable if you are an avid walker. The stay is 10 minutes from the closest station, Omonia, and approximately 30 minutes to Lycabettus Hill.
