The house was very nice and had a great lake view. During the day, it was a great spot for a short getaway. The kitchen was well equipped, the pier was nice and easy to access, and the lake was gorgeous. We rented some kayaks and had them delivered to the house so we got to enjoy the water on our own schedule, which was essential because of the rain; we kayaked every time the rain stopped and it was beautiful.
The house itself was perfect.
The beds, however, were a different story. My daughter described the pillows as "a couple of jumbo cottonballs stuffed into pillow cases." The mattresses were uncomfortable and the linens needed to be washed. There was actual dirt in the mattress pads of the bunk beds, like someone had been getting into the beds with their shoes on. The couches could use a good vacuuming beneath the cushions.
All of those issues were easy to fix -- we washed the bedding before we slept, then ran to Walmart on the second day and got a few new pillows -- and while annoying, did not diminish the fun of the overall trip, nor discourage me from wanting to go back to Deep Creek.
