We had a lovely time staying at Efi & Anna's place. The location was perfect - right across the street from the Acropoli station and the Acropolis museum. The apartment is situated on a street with many restaurants and shops, quite close to the Plaka area. Efi & Anna were very responsive to questions and arranging transport to the airport for us. They also gave us some great recommendations for restaurants to try in the area. One thing to note is that the apartment is in an older building so you will need to turn on a switch to heat the water before taking a shower, but overall we were really enjoyed staying here. Would recommend for anyone visiting Athens. Thanks again!
