Yuki's ping pong place was a good place to relax after a week's skiing. It's very spacious compared to most Tokyo hotels (at least for the price) and the ping pong, karaoke and projector were good to entertain the kids.
The locale was good. There are Supermarkets, restaurants and convenience stores very, very close. Whilst it's got public transfer nearby, the New Keio Line isn't that great for getting around town.
The only downside was the temperature in the building. As the walls, ceiling and floors are concrete, and we visited in winter, the place was cold. We had all the heaters going but never felt warm. I'm sure if you visited at other times of the year it would be fine.
A great place that I would visit again.
