Even though we didn’t see Efremia, we met her husband. He was incredibly nice; we arrived late and wanted something to eat. He brought us with his car to some places for dinner and made sure we were able to eat somewhere. The apartment is very cute and very clean. Little far from the main attractions in Athens, but since the metro is only 3-4 minutes away (waking) it was no problem. Would definitely recommend! We had a lovely stay :)
