As we write in our profile, we have no control over neighbor's parties esp during holiday weekends, as it was during your stay. Apparently, the loud music occurred in daytime and was off by 10pm. We are private, barely know most new neighbors in a city with high turnover given high rents (typical city life) and so we don't want guests revealing to virtual strangers that we are out of town traveling as it is a risk for thievery, etc..
Thank you, Mathieu and Francoise! You were excellent guests. I could not leave you a review because Airbnb changed the rules which allowed me to review guests from 1 months after they leave to only 14 days and we were on holiday for Christmas time. I will ask Airbnb if I can leave you a review because I was not aware of this change.
