Hotel is very comfortable. It is just as you would expect a rather good western hotel with much better beds than expected in Japan. Rooms are not tiny. Internet is excellent and staff was very friendly and accomodating.
Hotel is located a bit from Nakajima park. This is not a problem during summer but a huge setback during winter due to poor road conditions if walking the 250m stretch from the subway. Especially with luggage. The hotel offer a free shuttle service to Sapporo station during morning and late afternoon hours to alleviate this.
Still, I would try to stay at this hotel again when visiting Sapporo.
