We stayed for 2 nights just following Christmas. The ski trip was a Christmas present for our kids. While ultimately, the stay was fine, we had a number of issues. 1) An hour before we were to check in we received a notification that the toilets were not working and that they advised us to switch to another property 45 minutes away. We told them that would defeat the entire purpose of the ski trip and so they said they would try to fix things. (which they did later that evening around 9pm). 2) When we did arrive for check in at 4pm, the keypad was malfunctioning. We waited in the driveway in subfreezing temperatures, with little kids until their handyman was finally able to fix the lock around 6:20. 3) We started to get situated, only to find there were not blankets for all of the beds. (They did send someone up the mountain with blankets for all of the beds around 8:30 - 9pm). 4) The internet did not work most of the time, and when it did it was so slow it was un-usable. 5) There was a loud fan/vent sound that would wake us up throughout the night.
The shame to all of this is that the rental management company was fairly prompt and most everything else was fine, but these where pretty big issues that really caused us a lot of stress. We were promised that they would be able to compensate us for that in some way, but they stopped communicating at all by the end. I hope they get the bugs work out and choose to make this right.
