This was my second stay. All was good until my 2nd night when the host had a gathering at her house in the evening. It was very, very noisy until late. Then my unit started filling up with the smell of cigarette smoke (It certainly wasn't BBQ smells) which I couldn't get rid of despite turning on the noisy cooker hood and bathroom vent. I had difficulty breathing. It certainly was a very uncomfortable night. It would have been a considerate if the host had warned me of her plans for that day, so that I could decide if I still wanted to carry on with my booking.
