Stayed in family room. Just like the picture, small room with bunk beds. Kids liked the bunk beds though. The hotel is located in quieter part of time, and is much safer than notorious Frankfurt Central Station. There's tram and subway close-by to the city center so location is quite good. Also nice restaurants near the hotel. Staffs were kind and very efficient with there jobs. Breakfast was better than most of the hotels we stayed in Germany, would recommend it.
Over all, above average stay. Wound recommend.
