Unable to lock door on first day. Only responded the next day. We were on the same level next to a Company. There were loud construction noises as early as 7am even on weekends, including Sundays and Christmas day! Construction materials were shrouded on corridor, constituting fire hazard. We met our fellow countrymen who feedbacked they could hear the noise 4 stories up. Fortunately though both our floor and water heater were working, unlike theirs.
