Disaster from beginning to end. Check in time was 7 PM (very unusual). We arrived on time, no keys were available, no answers to our call. Building manager tried to help but said AIR BNB IN THIS building was illegal. By 8:30 pm, the host had been contacted but said he could not provide keys and he said he would cancel the reservation which left us stranded in Chicago at 8:30 pm (unknown city to us) forcing us to search for a hotel room. I believe this host is a scam and AIR BNB should not allow him to scam other guests _ greatly inconveniencing and endangering them. A total disaster!
