Derek was right about his first morning waking up due to a somewhat chaotic situation above. The mother had just given a Caesarian birth and the father was sick with a high fever. The situation was resolved the next day according to the parents upstairs, however, there was still too much noise for Derek. I did offer to switch apartments with him, living right next door, Derek however declined (without actually visiting the other apt), which I assured him was very quiet. I have updated the profile to indicate two toddlers living upstairs (that go to daycare). Previous and subsequent guests have not had an issue with the kids upstairs. The parents do make sure that everyone, including them, have some peace and quiet. My apologies to Derek for his unremarkable stay.
