Response from Dimitri:
thanks for the feedback. Was the noisy morning on Saturday, your last morning here? Or maybe Friday morning, the day before you left? It's usually just me and Angela upstairs, but we had family with children visiting starting on Friday evening. Saturday morning we were all getting up early for the Brooklyn Half Marathon, plus the kids were probably up early, too. And Friday my wife and I were probably up early to clean the apartment before the family arrived.
Sorry about that!
