I really liked the place. The days were warm, but with the aircondition , there was no problem when inside the flat. Wifi connection worked very well and it was great the TV had netflix!.
Koukaki is a very central neighbourhood, so you can get easily walking to Akropolis, akropolis museum, plaka, archeological museum, etc. Also, for eating, if you want, you can do it in the neighbourhood. There are cafes, bakeries and restaurants in close proximity. All good for me.
