There is a music club (Bearbie club) at the basement of the the building that opens at 12 am and closes at 6am from Friday to Sunday. The flat is on the 1st floor which meant that we couldn't get any sleep due to the music and the crowd outside the club. When we complained to the owners of the apartment they acted as if the didn't know about the problem and suggested to us to wear earplugs and shut the windows (we had obviously done that) and then they proposed some weird things such as to record the noise and go to the club and ask to turn down the music.
Also no central heating. A very noisy air condition was available that did not warm up the apartment efficiently.
