Sotiris place was great for our short stay in Athens. It was centrally located, a block away from the main shopping street and a short walk to the Acropolis. He responded quickly to all our questions, had great recommendations for us and was waiting for us when we arrived at night (even though it was late). The room was big, spotlessly clean and had an incredible view of the Acropolis too! Sotiris had helpful info, converters for pour electronics and even stock the fridge with water, juice and even a bottle of wine :)
We would definitely recommend this place and hope to be back!
