The previous occupants forgot to leave the keys, the host was on holiday and the guy replacing him didn't have a spare pair, therefore we couldn't get in to the house and couldn't check in. Also this guy temporaly 'on charghe' of the flat left us there saying that he couldn't do anything and he had things to do, the host replied to my messages and calls several hours later. We had to call airbnb, cancel the booking and make a new one. The flat is located in a nice area but i can't really say anything about it because I didn't see it. This wouldn' have happened if they had a spare pair of keys. Very unorganized host...
