Room was clean and quiet, I had a good sleep. Like someone else said, the facilities are not brand new, but were clean, looked after and in good working order. All the staff that I met were helpful. Only thing that was a bit confusing in the Trip.com booking system was description of bed sizes, but the reception kindly helped me get through this issue so I have no complaints. As for the surrounding area, yes, it's the train station area, but at the same time that's where most of accommodations in Frankfurt are. Overall, it was a good stay.
