I had a really good time at Super Hotel.
During my stay, I needed some help urgently due to a cancellation of my flight out of Sapporo. The hotel staff was kind enough to help me with phone calls and translation.
The only drawback was that there was no Wi-Fi in the room (unlike what was stated on the website). The directions to the hotel could also have been stated clearer (exit 4 from Susukino station, walk in direction of Toyoko Inn and turn right at the junction. Keep walking straight until after Lawson's; Super Hotel is located on a street down the left turn.)
