I lived in Greece from 1997-1999 and have been back a few times over the years, pre-Airbnb days. This was my first AirBNB experience in Greece and it was wonderful. The place is very central to Plaka, you literally step outside and walk a few steps to the busy Plaka shopping/restaurant area. About a 5-10 min walk you are at the acropolis, 10-15 min walk to the metro line. The location saves so much $$ because you can walk everywhere, no taxis needed.
The Airbnb itself is quaint and very well-kept and safe. The only suggestion I have would to have a fan in the loft area to help bring the cool air up to the loft faster. However, after a couple of hours, the loft area will get cool with the AC.
There were very thoughtful amenities available for us - US to EU converter (just the plug converter not the voltage), iron, tide pods, drying rack, first aid kit, etc. Wifi strength was very strong. While we didn't spend too much time in the AirBNB, we did feel quite at home.
Thank you again for making our stay in Athens comfortable and amazing.
