Location is amazing. Close to the metro, Plaka area, Acropolis, etc. The area is very safe and especially at night. I enjoyed my stay because of the location.
The apartment is small, I would recommend for 1 person. I had issues with the shower because I'm tall and I was almost touching the ceiling. There also isn't a shower curtain so you can easily flood the entire washroom.
However, Fani was great and she replied right away. Her store is a block away and she let me store my luggage at her store as I arrived a few hours before my check-in. Very trustworthy. I had an amazing time in Athens!!
