I stayed in apartment for almost a week. It's basic but good value for money.
When the water heater broke Dimi was very responsive and got it sorted as quickly as possible.
The apartment is walking distance from the Acropolis and the tourist attraction and area around it which is handy.
As a female solo traveller I didn't first feel great about the area but once I found my way round it was okay.
Athens in general has an issue with pick pockets and I watched one incident of a guy who had stolen a bag and was running away between the apartment and the tourist area.
The supermarket next door is handy although pricey as it's all organic. As a Coeliac I was very happy to find gluten free products there.
There is also a bigger supermarket about 5 minutes walk away.
The over the bath shower has low ceiling. I'm 1.84m and could just about stand up for a normal shower but had to crouch to wash my hair.
Overall Dimi is quick to respond to messages and very helpful.
