As I understand, it was anew apartment, hence they had no feedback.
Unfortunately, it was a very unpleasant stay. It was too cold at first, some things were missing (nothing for a dishwasher, or a washing machine, etc.). Sometimes, and unfortunately in crucial times, poor communication. Leaking ceiling (not their fault), toilet was clogged like 3-4 times in a month, 3 neighbors were making some renovations so it was noisy.
