On my first day at the hotel, I experienced a robbery in my room due to an inoperative safe box. The lack of accountability from those in leadership only intensified my frustration, a reaction that was, unfortunately, expected. I spoke with the receptionist and administrative staff, and they all indicated that they had not seen anything.
I cannot recommend this hotel. If you choose to stay at AC Hotel Coslada Aeropuerto (Madrid), please be aware that some individuals may not be trustworthy. There are those who might take advantage of the situation, potentially entering your room and inspecting your belongings, hoping you won't notice.
As an experienced traveler, I cannot recommend this hotel at all.
