Elena's place is the best you could find in Athens.. It is located in Kolonaki, in a beautiful apartment. I cannot tell you how beautiful the interiors is. It is very obvious that it is designed by a woman for women and lucky men. You have everything you needed in the apartment and even a local mobile phone was ready for me when I checked in. The manager of the apartment made my life so easy by organizing everything for me, a driver, suggestions etc. Anything you can ask for.
I will have Elena to design my next apartment. It is so lovely staying at her place in Athens, and my words are not sufficient. However, only tidy people should stay there as I really do not want untidy people to damage anything in that apartment as it is my place in Athens from now on :)
