Stavroula's Airbnb is great. Very stylish and modern. I enjoyed my stay in Athens. The kitchen has everything one need and more. The garden is nice to hangout or in my case to work.
The apartment is not very close to the next metro. Around 10min by foot. It's very close to Filopappou Hill thought and when going up and on the other side down you arrive directly in the old city. I did this the mostly and it's a nice walk.
