My husband an I stayed here for our own "closing weekend" for backcountry touring at Alpental and Hyak. The place is clean, the bed comfortable, hot water and shower pressure good, and really no major complaints for a place to crash after skiing all day.
The things that weren't stellar were the kitchen is not stocked, the cooking pans are in terrible condition, spices old and mostly out, & there were only Keurig pods for one coffee each. I would have appreciated a bit more care in these things as the market close by is expensive and doesn't have a lot of choices. Also, adding a french press or regular coffee maker would be nice.
There is no WIFi or Dish, and the DVDs were in terrible (scratched) condition. We weren't really concerned about this but if you are looking for TV entertainment, bring your own selection.
Be aware also that the I-90 is RIGHT behind the cabin, so peaceful it is not. Also as others have mentioned, the walkway is not plowed at all, and with spring melt, was a precarious jump onto the deck from the icy snow bank. If anyone in your party is less than an athlete it may be dangerous/inaccessible.
For the convenience of staying at the Summit it is a fine place. We would probably return. With just a few more personal touches this place could be 5 star!
