We never met the owner of the apartment and all the check-in procedure was done by using 4 codes to open 4 different doors including the main entrance of the apartment. After our check-in the first day we left the apartment for a walk and shortly after we received a message from our credit card Bank for a transaction to a store that we haven't done, so immediately we returned to the apartment just to realise that someone has broken into it and took cash and two credits cards that we have left in the room with our stuff. In the apartment there was a safe box with no insturctions and obviously we couldn't use it and the windows of the apartment were firmly secured during our whole staying. However, that doesn't change the fact that someone got inside and messed with our stuff. We contacted the owner through telephone to complain, but instead of him a lady answer and told us to not worry and go to the Police. We went straight forward to the nearest Police Station to declare the incident and we kept trying to contact through telephone and airnbn platform the owner, but couldn't reach him. We demanded through platform to be refunded for all that we got through and the refund was part of money that we paid for our staying there, however that never covered the amount of money that was stolen of! Our trip to Paris was ruined from the first day, not only because we left with no money, but also we were afraid to stay there knowing that someone might enter again the apartment while we were inside! However, the most outrageous of all was the physical absence of the owner! I wouldn't recommend the apartment to anyone, because of that. We left Paris in bitterness, although the apartment itself at first sight was a decent one.
