Nice hotel, easy to locate and get into Frankfurt central via the underground.
Positives include a good sized room, fast internet, free minibar, comfortable bed, quiet room. Room had plenty of lights but still seemed dark in places.
Couple of issues with the room initially, safe not working and crisp pieces in a couple of places. Mentioned to front desk and the safe was repaired but crisp pieces still there when leaving. Also, used cups were left on one occasion.
I would stay again but was a little disappointed with the thoroughness of the cleaning.
