I had a blast staying at Konstantinos. He's been really kind and accommodating. We shared a lot of chats by the sofa and I got to learn some greek vocabulary as well hahaha
The place is really lovely, I shared the flat with other really kind guests. The room was really cozy and had a nice balcony.
Location-wise, the zone is nice and quiet, 20 min from acropolis.
If I get back to Athens in the future I wouldn't hesitate on coming back to Konstantinos!
