Helio Hostel is a good option for solo travelers on a budget. The bunk beds are quite large and provide everything you need for this type of accommodation. There are shower facilities plus towels supplied. There is a thin curtain to pull across to give you some privacy. The staff are very friendly and will assist you, though they are not available after 23:00. They have male, mixed, and female dormitories. This hostel is very convenient as it is right in the middle of town so it’s easy to access all the sightseeing, shopping, and the nightlife. There is an office space on the second floor with a coffee shop on the ground floor. 

The coffee shop is fantastic and perfect for those who need a quiet spot do some work, study, or relax. There is plenty of seating with small tables and comfortable chairs or counter seating. Each has a power point which is not common in Japan so you can charge whatever device you are using. Equally convenient is the wi-fi here. There are tonnes of books and magazines in the lounge area lining the walls which are free to read at your leisure. The coffee here is ok, the Hokkaido latte is the best coffee they have here and is very good. They do not sell food here unfortunately. Overall, this is a clean and modern hostel in central Sapporo with a great cafe on the ground floor.
