Good value for money. The room was spacious, the bed and couch were comfortable.
This must have been a great hotel about 30 years ago but it's lacking maintenance as per other reviews; carpets and furniture are stained, furniture is damaged, etc. This, however, was not a big issue for me.
It is also true that it is located at the ages of the Frankfurt central station 'zombieland', full of junkies, pimps, prostitutes and other dodgy characters, at any time of the day and particularly at night. This is not the hotel's fault, but the local government's responsibility, as they have allowed this issue to worsen year after year. It does, however, impact one's experience. The location is convenient, but the area doesn't feel safe.
Overall, I would recommend it to budget conscious travellers. I would stay there again but given my poor first impression of Frankfurt, I doubt I'll ever go back to that city.
