This place is in a great location - easy walking distance to all the major sites, the farthest being about 25 minutes to the Psryi area.
The apt is very clean, cutely decorated, the bed is very comfortable and its very quiet at night, although bustling during the day. The A/C works well after long days in the heat. Make sure you bring shower soap/gel as there is none, and pay attention to turning on the breaker for your hot water for showers. We didn't cook but there the kitchen does have basic necessities.
We would absolutely rent again, especially now that we know what to be aware of.
Take the bike tour of Athens - its a must do! Not hard and they have e bikes if you need them.
Overall it was a great stay!
