The hosts were very friendly and attentive to us, they made recommendations about Athens and offered us water and some small details when we arrived.
They offered to pick us up and take us to the metro station, without asking for anything in return.
The apartment is like in the photos, it is old, but it is perfectly conditioned, clean and with the basic things.
About the location, there is a hard up hill for arrive to the apartment, but the views of the Acropolis and the port from this point are very beautiful.
