Upon arrival in Rome, we experienced a heatwave. Our hotel room had a malfunctioning air conditioner with an "insufficient coolant" error and a temperature of 28°C. After reporting it to the reception, we were upgraded to another room, but it had the same issue with a temperature of 29°C. We couldn't sleep due to the heat and noise, and the windows wouldn't close properly. The next day, we reported it again, only to be told the air conditioner was working and a technician would come "sometime today." After calling an Italian friend to translate, we finally got a room with a working air conditioner. The staff spoke too little English to resolve the issue effectively, and the new room was also noisy.
