The instructions/check-in was quick, but thorough. We did not have any problems during our stay, so we did not have to use the emergency numbers. However, we were never worried we would not get support in case anything happened.
It seems like they are renting out the apartments on all floors. We got one on the top floor, which meant that we were not disturbed by the noise from the street at all. All in all, the rooms/kitchen/sitting area were Ok, with lots of space for the kids to run around.
The only thing was the beds, which were really, really uncomfortable. I usually do not care at all, but these were a bit like sleeping on the ground.
(And, yes, to be honest, the apartment was a bit worn down, and a bit dirty at some places. Although it was nothing major or unsafe. Just mentioning it - you should not expect too much.)
