Xenia, Myriam, Eva & Rena were four powerful women which played an important role in my life as my mentors. In addition, they are worth mentioning as role models because they offered a lot with their ethos, hard work and dedication to society. Therefore I named after them my apartments in Athens. Their story is told and done justice!
