PROS - Everything as described. Although Dimitra was not there in person, she arranged for an English speaking person to meet us in the apartment. She was very reactive to our chat messages. The place is sparkling clean and recently refurbished. The bed is very comfortable. The place is very well-equipped, suitable for cooking.
NB - You may see in Google Maps that this is very close to the centre of Athens - but what they mean is the BUSINESS centre, not the HISTORIC one that is approx 20-minute walking distance from Dimitra's place.
CONS - Very dodgy area. People in the streets drinking and doing drugs (cooking heroine, injecting stuff, etc). My girlfriend was scared to walk around alone. And I was not feeling safest either. Also, the neighbours are rather noisy, being loud every night until small hours.
