Stayed 4 nights with family. Our "comfort double" room was clean and comfortable. With two large suitcases laid flat on the floor, we were still able to move around (that may not be possible in other Japanese hotels, especially in big cities). The hotel was close to train station and tracks but was quiet.
We did not try the western style breakfast buffet, as that did not suite our taste. But there were plenty of dining options nearby, and we also picked up fruits and beverage from the supermarket next door a couple of times. In the cafe area, there were some hot and cold beverage available to guests between 10 am and 10 pm.
We did laundry once. There were 2 machines on 6th and 9th floors each. A single machine was capable of washing and drying in a 2 hour course, and the recommended maximum load was 3 kg. The course cost 600 yen, with addional drying available for 100 yen per 30 minutes. Being able to paying with IC card (ICOCA, Suica, etc) was convenient.
Overall, we enjoyed our stay and will definitely consider this hotel if we visit Kobe again.
