@myska Hey, I came back yesterday. I was at an event with 0 energy to blog or social media, I'll post some pictures soon.
The experience was overall nice but Athens can be checked off my list. I think if I go back to Greece it will be to visit the small islands.
I used the bus and metro, quite the experience! Google Maps worked very nicely even if the buses were in bad shape.
Thank you for the recommendations nonetheless.
