The apartment is very beatiful, exactly as described by Nassos. I stayed there for five days with my girlfriend and we had no problems.
It is in a perfect position to reach the city centre with the metro and is also near to a market; the area is safe, also at night. The apartment is clean, easy to find and provided with towels, gel douche, some essential things in the kitchen (salt, oil,ecc.), hairdryer, clotheshores, iron and a washing machine.
The kitchen has a coffeepot for american coffee, a single electric cooker (you can cook a pasta for 2/3 people without problems but you can't cook multiple dishes, like a sauce for the pasta) and a kettle.
Nassos gave us every instruction we needed and has been also very helpful with us: he answered our messages quite soon.
Finally, this apartment is perfect if you want to visit the city.
