The room itself was fine, but unfortunately the nights were not very restful. There was a constant cracking or clicking noise during the night, possibly from the air conditioning or another technical system. It kept waking me up repeatedly after I had fallen asleep, on both nights, until I was simply too tired to notice it anymore.
The mattress was also much too soft for my preference, although I understand that this is subjective.
In addition, the kitchen was being renovated, which meant that breakfast was limited on the first day.
Overall, the stay was acceptable, but the sleep quality was clearly affected by the recurring noise.
