The location of the apartment is great, you only have to walk out the door and in 2min you are at the acropolis.
The WiFi is not good.
The second day we were there, we had no hot water and we had to wait for the whole day to get it going again.
And the apartment is a bit small for 4 people, there is very few space to store clothes or anything like that.
But overall it was a great experience.
