As for the noise: Yes, we have a 4 year old that was running around the apartment. I guess the hard-wood floors make noise, and I apologize if this caused any problems. No one talked to us (In fact, we didn't see any other residents/guests the entire time). If someone had let us know, we would surely have complied.
As for the trash: Apart from a very small trash can in the bathroom, the kitchen trash can was small, and no trash bags were provided (There were some smaller grocery bags under the sink). In retrospect, we should have made more of an effort to locate an outdoor trash can. Our 4 year old wears a diaper at night for precaution, but most mornings it's dry. I don't remember if it was wet or not on the day we left. I think this could have been avoided if you provided a larger trash can and proper trash bags. In any event, we could have done a better job looking for an outdoor trash can.
As for re-arranging the furniture, we did move a chair to make room for one more place at the table. It's news to me that it caused a scratch. Sorry about that -- it was certainly not intended.
