Dear kchan167967,
Thank you for your stay in Radisson Blu Plaza hotel.
I'm happy to hear that your stay was pleasant and overall your visit was great. I'm really sorry to hear that there was stain in the toilet. I will check this with the housekeeping and make sure that for your next visit the room is cleaned very well. At the moment we really make our best with the cleaning, it is the most important that or guest's feels comfortable.
Hope to see you again soon in the heart of Helsinki, Radisson Blu Plaza hotel.
Kindly Regards- Alia Hussain /Service Manager
