First of all, one should be aware that this is not a private room inside a host's residence. There is a separate two bedroom apartment in the rear of the host's house that has a small kitchen and two bedrooms (the host rents the two bedrooms out separately). I communicated to the host that we would be arriving at 1pm to drop our bags and he let us know that would be fine. When we arrived, there was a young woman in the room that we were supposed to occupy. In addition, the apartment had clearly not been cleaned. There was food out on the table and the kitchen counters. We were able to find the host by going to the front of the house and he walked to the apartment with us where the young woman said that she was "sick." After first saying that she "couldn't leave" because she was sick, she then said she would leave after the host said he would need to call an ambulance if she "couldn't leave." We were in disbelief. We could not believe that the host was not aware that his previous renter had not checked out and that housekeeping had not been there to clean up. He knew we were arriving at 1pm and he never checked to make sure that our room was ready. And not only was it not ready, but there was a woman in the bed and the place was a mess. I have had great experiences on Airbnb, but this was not one of them. Luckily, we were given a full refund. Unfortunately, we had to scramble to find a hotel room for the night and we ended having to stay 30 min outside Boston, when we had planned on staying in Cambridge. It was very disappointing.
