Hello, I travelled from Cologne to London with the line 815, from 7:15 Köln/Bonn Airport to 17:20 Victoria Coach Station, yesterday the 17th of August. During the entire ride, the smell of urine filled the bus and made it exceptionally unpleasant. Either the toilet is leaky, or the air-conditioning faulty. However, this is not the worst part. After having arrived in London, I picked up my backpack, which had been lying in the baggage compartment. It was soaking wet. The Bus-driver insisted that it was water, which would be bad enough, as all my clothes, my backpack, and several presents would were soaked. I believed him, mostly because I had been smelling urine for the last 10 or so hours, and I thought that the smell was still in my nose. However, the liquid that had soaked my backpack, and thus also all my belongings that I hadn't taken up during the ride, was in fact urine. You can probably gather that I am upset about this, both because I will have to buy a new backpack, and because I was forced to carry a urine-drenched backpack through London until I got to my hostel. As such I would request compensation for said piece of luggage, and in general ask Flixbus to PLEASE check the toilets of the busses for leaks, especially when they might go into the luggage compartment. This was a singularly horrible experience. Yours, Noah Thembile Buttschardt
