Everything was fine with the condo with a couple exceptions. First, the entryway was frigid. I know it was cold while we were there but the in-floor heat wasn't operating and the door didn't shut properly so the cold air just flowed into the condo. We mistakenly left our boots downstairs and our feet never warmed up due to the temperature deficit when putting them on in the morning. We learned quickly that we couldn't leave out boots down there as we may as well left them in the car or a snowbank! It was very cold even at the top of the stairs in the hallway between the bedrooms.
Lastly, the water pipes seemed to have froze on our second to last day there leaving us with one operational bathroom for 6 people. I let someone know about it and they offered to send someone over but as we were leaving the next day, we just dealt with it. But, we shouldn't have to just deal with something like that while on vacation. I grew up in MN and we never had any pipes freeze even when -56F. Seems the construction/insulation isn't up to the need.
