I made my reservation by phone after visiting the hotel website, mostly based on the excellent location just a few steps from the main railway station. (I was arriving by train from Frankfurt airport.) When I arrived, I was a little worried at first, because the hotel doesn't look very nice from the outside and the front desk area as well as the internal hallways look very old-fashioned.
My room was nicely furnished and in excellent condition though. The bathroom/shower was very nice and clean as well. It seems that the rooms have been refurbished just recently.
Nice surprise: the stuff in the minibar was very inexpensive - the price for the mineral water was less than what I paid at a shop in the railway station!
The room rate (incl. breakfast) was €62 on a weekend, which I found good value, considering the size and quality of the room. Unfortunately I slept too long to enjoy the breakfast, so no comment on that.
The one thing I didn't like, was that VISA is the only credit card accepted. Therefore I had to pay cash because I have MasterCard and Amex only.
