I feel your pain!! We live in a small 2 bed apartment also. Luckily cleaning and doing chores doesn't usually wake DD during naps or bedtime. However last night I was awoken my our neighbors partying and the upstairs neighbors stomping around at 2 am. It was terrible. DH has went upstairs in the middle of the night before to ask them WTF they are doing but they never answer the door.
Lucky you guys are getting a house soon! We are not so fortunate.
