After spending most of my vacation in more casual accommodations, the Route-Inn in Sapporo was a quality and professional hotel experience. Good staff, facilities, and breakfast buffet, and it's literally right across the street from JR Sapporo Station which means you get in from New Chitose Airport and the hotel is close enough that waiting for the crosswalk signal to turn green might take longer than the rest of the walk over. They have onsen facilities in the basement that I didn't personally use, but the coin laundry machines are located just inside the dressing rooms down there. The desk staff's English ability is functional enough, though asking about more complex concepts might be a difficulty.
