This hotel in "palaka area" is in a fantastic location. Its walking distance from all the nice hotels and bazars.
The hotel is 20 minutes max from the airport, 2 minutes from little palaka bazars, 5 minutes walk to the shopping district and Center square "where the subway/metro" is and just few minutes away from so many places to eat at.
Its clean, cozy and makes you feel home. Staff are friendly and so helpful. The place is safe and you may keep your stuff at the hotel to store when you are away touring around the islands or even traveling away from Athens for couple of days.
You may find one of the best restaurants next to the hotel called "pisirass", do not leave the area without tasting its food. Believe me you will never forget it or regret it.
Note: there are tow Electra Hotels in the Center. Choose the one in palaka and not the shopping district "its more quiet and away from all the noise at night and in day time".
