Kostas place is exactly like the pictures. I was by myself and it felt huge. I don’t think more than 2 people can stay here though. Since there’s only 1 bed. Kostas is extremely responsive and accommodating. Offers to pick you up from the airport for 30€. Location wise it’s less than a 20 minute walk to the center. Next time I come to Athens I will definitely stay here with Kostas.
