This one of the worst case scenario to arrive foreign country ,ressive information in email where is the key of the apartment. I check it and was not there, then I write to them again and they told me to open other safe box..which was not possible to open. I when to the cafe shop next to the apartments and told my story.
So I found out that I am not the only one and many people complain about the same problem..no keys. Cafe shop close and was getting late I started looking for a place to sleep..walking in the streets with my bag and suitcase.i was afraid not to spend the night in the streets ,I didn't hat internet only in the cafe shop which close, phone battery also died..didn't know the area which was little bit scary, so walking and asking found hotel..unfortunately no free room only expensive hotel suite,then again walking asking people around in the street for room for rent.
Finally successful in 22.00 pm I found place with internet..charge my phone write again to the apartments support ..they apologized and give me other code to try open the safe box..then again I when to there again not success open, have many pictures for a prove. Actually I never stay in this apartment in the same floor where was the apartments was a shared kitchen and shower which was so dirty ,I was able to see because walking in the floor looking for someone to help me ,ask someone. This was my horrible story,on the end they wrote to ask for check out..I answer that I never was there isa joke
