Great central location, near shops but also close to the must sees like Acropolis, Olympic Stadium, Plaka, Monastiraki etc. Simple, effectively run premises. Very nice and helpful staff, they helped arrange tickets for guided tours and transportation to and from the airport. Room was modern, cleaned daily, complimentary coffee capsules and water bottle. Only downside was the noise from the elevator machinery, a kind of low humming but we got used to it.
