Hospitality issue - John and Mabel accused us that their 3-seater sofa AND 2 arm chairs had a very strong urine door. They said that guests will not be able to sit and relax ON EITHER the couch or arm chairs due to the strong smell of urine. They invoiced us for 3-seater sofa AND 2 arm chairs for $150. We apologised as our 18 month old is toilet training and must have slipped up and offered to pay them $100 to clean the entire 3-seater sofa though he only sat on one seat during our stay. We did not allow our 18 month old to sit on the 2 arm chairs as he could fall so we told John and Mabel it was wrong to charge us to clean an additional 2 arm chairs and told them their accusation that the 2 arm chairs had a strong smell of urine was false. They then invoiced us $130 to clean the 3-seater sofa. John and Mabel declined our offer to pay $100. John and Mabel told us they are not even billing us for their effort, time and inconvenience for taking care of the issue and said it shouldn’t have happened in the first place. They also claimed that their 3-seater sofa was ‘also dirty’ which is also false. Despite us offering to pay $100 for the incident, John and Mabel have decided to involve AirBnB to chase after more money. We tried to settle this with John and Mabel in an amicable manner as we also understand our responsibility however they showed a lot of hostility. We do not recommend this house if you have young children based on our experience.
