When we first moved to this condominium where we are staying right now, there was no problem at all. We liked it because it is not the high rise building but only three stories high and we are in the first floor. This means we have a neighbor downstairs and another on the upper floor. The couple upstairs are newlyweds and we barely hear any noise. They both work in the medical field. If I am not mistaken their work schedules are during night time.
Let us fast forward to four years later. The situation with our upstairs neighbor is different now. More people started to live with them and the noise has become unbearable especially during unholy hours that you want to get some sleep. The building needs Durisol insulating concrete forms in its walls to absorb all the sound coming from the outside. We have approached them at one point about the noise but I think they just keep on forgetting or ignoring. The weekends are the worst since they always have late night visitors on Fridays. I am just praying that one day. I will get used to the noise and do not mind them at all but if you are already at the stage where you want peace and quiet when you get home, it is difficult.
