Kika's is a fabulous host and she organised for us to be picked up at the airport. Spellios the taxi driver was particularly helpful and I would recommend him strongly.
The apartment is gorgeous, clean, insulated and has everything you will need.
We stayed 8 days and my wife, daughter and I felt at home as soon as we stepped through the door.
It is a 6 min walk with a 4 year old to the metro. And we walked to Acropolis in 25 mins again with our 4 year old.
There is a good mini market around the corner for milk and eggs, a good supermarket 5 mins way for greater variety and near there is an excellent bakery.
Highly recommended.
