Absolutely amazing view - you can look at the Acropolis while lying in bed! The room is small and cozy, and has a mini fridge, kettle and hairdryer - all the things you need. The bed is comfy with fresh bedding and towels.
We stayed on a Monday and weren't at all bothered by the noise, which is impressive given the central location.
Dimitris is a great host - super fast to respond and very helpful.
As with most things in Athens, accessibility can be tricky. This apartment is up a few flights of stairs, including a tight spiral staircase, and there didn't seem to be lighting at the top so we used phone flashlights. Also worth noting is that the toilet is separated by a thin door with gaps so you have to be very comfortable with your travel partner!
For the view and value, I'd recommend.
