The Poseidon Hotel was a wonderful place to stay for a week in Athens! I was traveling in town for work and had a 15-minute walk from the hotel to my work. The surrounding neighborhood was quiet, friendly, and beautiful. I also enjoyed walking along the beach, using the tram to visit the center of Athens, and lounging at the plethora of outdoor cafes nearby. The staff was kind and helpful and the hotel was very clean. I would definitely visit the Hotel Poseidon again!
