Everything is easy with María. She answers quickly, she is nice and helps you with every doubt you have. She leaves you the keys in a security box where you can leave them too the day you leave the apartment and this makes easy the arrival and the check out because you do not need an exact hour. The apartment was clean, nice and comfortable. The zone is a little bit dark but I walk through the streets in the night and nothing happens. It is also pretty close to the centre, you arrive at Monastiraki in 15-20 min. So it is a good place to be if you want to visit Athens.
