The place is in a great location because it is out of the most touristic area, but you reach the Akropolis within 10 minutes walking.
The neighbourhood is quiet (for Athens standards) and very safe. We miss some spaces for our 5 year old to play, but you cannot have it all, and you have the esplanade at the foot of the Akropolis to play, etc.
The accomodation is great, all kitchen garment is new and not very used, so if you feel like cooking it is great. Everything is very comfortable, the beds for instance, and there is plenty of space.
It is a bit of an old building and house so isolation is not the best, so you can hear the neighbour at night a bit (nothing extreme). The appartment is a bit dark, compared to the pictures. The front terrace is great and you can enjoy there from a nice breakfast in the morning or late dinner / drink.
