Giannis is a fantastic and warm host. It's like visiting a favourite cousin in Greece. His home is a little gem in central Athens, where almost all the sights including and especially the Acropolis are within walking distance. The main shopping districts and Monasthiraki square too are within walking distances. Besides for your visits outside Athens the metro can be accessed in a matter of a 7 minute walk. But most of all this kindly helpful host will find and print any info you need and will look out for you and make you so comfortable , you may never want to leave.
