We stayed at Katerina's place for 3 nights and loved the apartment. Her mother was helpful, friendly and very welcoming, she's a wonderful host and our sons adored her. The apartment was clean, well situated (15 min walk to Acropolis Museum), is very well stocked, had plenty of info about Athens, has a beautiful terrace, very comfortable beds, was quiet at night and it felt like a home. We would highly recommend this place.
