The apartment is located at Hiragishi district in Sapporo, and only a few stops away from Sapporo Station. The tube is about 3 mins walk from the main door. Amenities are provided, as well as cooking facilities. The size is pretty spacious for Japan standard.
Would not hesitate to stay here again. My only complaint is I found the heating a bit insufficient, but nothing that can't be solved with putting on some extra layers and using the duvets provided.
