Booking.com Green Suite Hotel Room Had Dirty Smell and Poor Hygiene Conditions

I made a reservation via Booking.com for Green Suite Hotel in Beyoğlu, Istanbul, for 2 nights starting on 24 September. From the moment I entered the room, there was a very disturbing dirty smell and the room was clearly not properly cleaned. This situation made my stay extremely uncomfortable, and I did not feel that the room met basic hygiene standards. I tried to reach Booking.com customer service by calling the number provided and through the app, but I could not connect to any representative and did not receive any support. Because of this, I was left alone with the problem at the hotel and could not get any solution during my stay, even though the service was already very bad. I am requesting a full refund for this 2‑night stay, as the room conditions and the lack of support from Booking.com did not match what was promised and seriously affected my travel experience. I ask that my complaint be urgently reviewed and my refund processed as soon as possible.
