Iason's place is the reason we use AirBnB when we travel. It's their personal place and we loved every detail of it. The house is close to a lot of bars and restaurants and very centrally located. Do mind that you should probably not leave your rental car outside, there's some nice parking 24/7 garages around the corner though. Besides his place being great, Iason and Dimitris have also been super helpful and accommodating to any questions we had. Really if you want to stay somewhere in Athens, this is your spot!
