NAME_1, thank you we very much enjoyed the house and are looking now to re book a house for next year, I am ok with the charges except the BBQ clean as we cleaned the BBQ extensively before we left and was definitely in same condition as when we got there, is it possible reimburse me for that? Please let me know, then I will get you info to return the deposit, thank you
