Konstantina's place is a really huge apartment with all the necessities and amenities, in an upper middle class neighbourhood. Everything needed is within an easy walk: cafes, supermarket, bakeries, greengrocer.
And it certainly is absolutely safe: since apparently some higher level political figure also lives in the building, there is a 24/7 police guard at the entrance.
Thank you Konstantina and Giorgiou for your hospitality.
