The host is great! we were able to check in early and check out late.
The apartment is big, lots of natural light and great view from the balcony!
In the kitchen waited a bottle of wine and some breakfast products.
what did bother us a bit is that it was cold in the apartment, although all the windows were closed.. cold air found its way in somehow. and the light wasn't working in the bathroom.
Other than that, I found the location not optimal, it takes around 10-15 minutes walk to get to the center of Athens but you'll have cafes & restaurants near the apartment.
