Excellent apartment. This was one of the nicest airbnb places we've stayed. We were thrilled to stay here and had a great time. The unit is very nicely furnished, with a fully appointed kitchen, two full baths and a washer dryer. Very centrally located and a short distance from public transportation and even within walking distance (30-45 minutes) from the Acropolis. We had no problem finding a bakery and grocery store within walking distance to stock up for our stay. The neighborhood is quiet and seems very safe.
The unit has large patio and sliding glass doors off all the main rooms and it gets tons of sunlight and fresh air.
Soula was very easy to deal with and we got into the apartment without problem or delay.
My only caveat - be aware that there is a steep hill from Syggrou Fix subway station leading to the apartment that would be difficult to manage with lots of luggage (luckily, our luggage was delayed and delivered to the front door the night of our arrival so we didn't have to deal with that). Soula recommends taking a cab from Syntagma Sq which I think is best of you have lots of bags.
