We have stayed in Snow Dog for 15 nights now and have no complaints whatsoever!
The place is run by Ski Japan, and all employees are Ski Japan as well. This made it super easy to arrange transfers to and from Niseko at the same time as accomodation- they did the lot.
We arrived into town after the 8pm close of reception (delayed flight) to find the staff had waited for our arrival at the premises- it blew us away. The apartments are clean, modern and very spacious for Japan. Beware the walls are thin however, so be respectful of neighbours.
To get around, the Snow Dog Shuttle goes to the Hilton (Niseko Village) and Hirafu hourly, and the bus drivers Luke, Josh and Ceasar are awesome dudes who will always help out when they can. Luke in particular gave our family great advice when we all came down with the 'Hira-flu", and also gave us some good ideas for local food places.
There are 2 cafes/restaurants on premises, but having a kitchenette made life so much easier for us. After a month away from home, cooking a meal was a luxury!
We still have 3 nights here but we couldn't have picked a better place. Yes it is a 5 minute bus trip to the nearest Niseko Village lifts, but 110% worth it for the amazing facilities and staff of this place. We had family staying in deluxe rooms in the Green Leaf, and Snow Dog ran rings around it both in terms of space and service.
