My brother, mom, partner, and I stayed 3 nights and 4 days. From the listing it appeared to have exactly what we were looking for, a place where we can cook, 30 minute drive to Mt Baker Ski Area, bedrooms for a 4 of us to comfortably sleep in, a hot tub, and a big dining table for boardgame activities.
The cabin/property was extremely well equipped for our snowboarding needs. There was a 4-slot bootwarmer. There were a lot of recliners/sofa chairs to lounge in, etc.
The people who help manage this property are super quick to respond and help out pre-trip and during the stay as well. I have T-Mobile and had enough reception to make calls and check emails.
The internet, despite the property managers saying it was going to be "spotty" we never had an issue. We brought up a chromecast with us and were able to watch Netflix and other entertainment.
Check in and check out process was pretty straightforward and had no issues. If anything, the key to the property was a little complicated but if you push in the key well enough it will turn the lock.
Felt like the could have provided us with more/better paper towels for the dishware. We brought our own pots and pans because we weren't sure what the kitchen was going to be equipped with. There's a lot of utencils, dishware, etc, but I will say bringing your own pans and pots might be a good idea as their pans are pretty scratched up.
Heating was great although the one room with the twin beds does not have a heater/furnace. There was a portable heater though which did the job.
Lastly, while our primary trip was for snowboarding my mom stayed back in the cabin and had a great time. There's a trail nearby so it seems like there's a lot of outdoor closeby activities to enjoy as well.
Friendly tip, we bought all our groceries from home as there's not a huge grocery store nearby. (There's a small market about 5-7 minute drive away).
