It was a pleasure staying with Asteris. His airport transfer service made my short stay in Athens very easy. The acropolis is an easy walk away, and public transport is close by to get to the beach or wherever you desire.
Alternatively, an Uber will get you to the beach for about 8 euro.
The room was clean, air conditioned (critical as it was nearing 40C during my visit), and had everything I needed.
Asteris himself is a lovely guy, and made my visit very enjoyable.
Thanks again Asteris for a being great host!
