A fine little cabin.
Clean space. The long closet is actually useful for organizing any clothes you might have. Rocking chair is comfy.
Though the air is cool at night, it can be somewhat difficult to sleep during the summer (a fact of cabin living, I suppose).
The upstairs neighbors were fairly quiet during my stay, but yes, you can hear some footsteps. It wasn't a big deal for me.
Kitchen is indeed slanted, also not a big deal. Just be quick with the fridge door, lol.
All in all, a fair value for the price (~$150/night). Spent most of our days in Santa Cruz, which is only 15-20 minutes away.
