Aprt is a 2stories: one room+kitchen are in the basement. AC-quiet. Boiler is in the kitchen heats water for the whole house:hot water in shower and heating. It works pretty loud, even if you close the door you still can hear it. It heats up water in cycles, so it’s going to run whole night. If you sleep on the same floor, you’ll hear it.We also had problems with boiler, as it seems to turn off gas pressure after 1person shower. On the 1st night when it happened we ended up sleeping in the cold aprt. Next day Can turned the pressure on. We fixed ourselves next time. 2floor has bedroom+bathroom.When we arrived there was no hot water in the bathroom sink and the water was leaking under the sink.We a sked Can of this can be fixed, next day he brought a master who replaced tubes and the facet. Hot water was clearly closed on purpose even before we complained, so I’m sure owners knew about this.upset that it wasn’t fixed before and I had to ask for it.Stairs in the aprt don’t have railings
