My arrival was 8/12 at 22:00(ad:Mavromichali 106-108)and i had to find a lock box next to the door,but it was at 104.I went on the 1st fl.and i had to go left and the right door it would have the Mint sticker and the name. No door there,I checked all the doors and none of them had sticker nor name.I tried to call the number,but it wasn’ t working.I called the viber that made the confirmation,about my arrival and i found a woman telling to make vid call.She told me to open 1 door when i tried to do that,2 men opened from inside.She told me that she would call me back.After 30’,another called me.She asked me to open a second door but there was living 1 other man.When i told that she had to come&put the sticker and the name,she told me that this was no possible.I called airbnb to help me but they couldnt find her & they didnt find me a place to stay, it was 1:00. Airbnb after all this put my money back.9/12 i went with a friend there.Fortunately the neighbours helped&we found it.
