This year, for the first time I am taking an extra holiday in Greece in addition to my usual September one, and am renting a self-catering studio in Piraeus at the end of April. It is on Omiridou. How safe would it be to walk back there either from the Metro after dining in Athens, or from any of the eating places in Piraeus? I'm a lone woman of mature years, but not afraid to walk by myself.
