Good contact with a very helpful and well-organized host, he replied to the message immediately and takes care of your stay. Apartment very clean and well located - 5 minutes on the metro. However, the area seems to be not very safe and if someone cares about the silence - it will be noise all night long (but it seems to me that this is a feature of Greece, here it is everywhere noise :) ). Watch out for the door - they are self-locking. And if you leaving the room and leave the keys, and the door to the staircase will be closed, you will get stuck in the corridor.
