We are talking about a host that do not answer to messages or to calls at all, knowing that he got someone checking in on that day. When I arrived I tried to open the lockbox with the password provided, no success, I even checked around if there was another Lockbox. After 2 hours of not being able to reach the host, I contacted Airbnb support and looked for a hotel where to stay that night. We are talking about January in Montreal, you can imagine the temperature. I, of course was aware of the weather, but not expecting to experience it that way. The host got back to me 3 hours later!!! With nothing else but excuses like " I did not see your calls for some reason, Airbnb did not try to contact me" but the best one was "maybe you used the wrong lockbox". Well maybe you should take a photo of your lockbox location. Post it on your check-in details so people don't waste their time. I realised later on the reviews that someone experienced something very similar to me, an empty lockbox....
