A very nice apartment, clean, spacious and beautifully decorated, really everything you need is available. 2 bedrooms with ok beds. Good kitchen with all equipment and large refrigerator. Great shower with rain shower head. Airco in every room as well as electric shutters on each window. An iron front door with superb lock gives you a safe feeling.
We did not meet the owner but the communication with him was very clear. We picked up the key from a safety box with a code which worked out very smoothly.
It is close to metro and bus connections and not far from the centre of Athens. We experienced some taxi drivers trying to cheat, so we used Uber which works well, it is only about 6 euro to downtown.
What we did not like so much was the neighbourhood: a bit grim and lots of beggars and groups of men hanging around in the streets at night. Not very cosy.
Concluding: superb apartment, great value, only downside is a grim neighbourhood.
