We had an excellent stay at Elpidoforos' place. The appartement is great, conform to the pictures and pretty well located (you can join the old center by foot in about 30min or walk 8min to the metro and then take a 5min ride from there). The quality/price ratio is excellent. Elpidoforos was an amazing host, sending us advices about how to reach the BnB from the airport, meeting us at the bus stop and then spending so much time explaining us things and giving us informations and insights about Athens. We would 100% recommend staying there if you ever visit Athens.
