The cabin was clean and cosy. The location was was nice, very quiet, and within walking distance to the general store and pub. We had a little trouble getting in since we must've missed an email about the key code but Karen was very responsive.
Just be warned there is no phone service in Port Renfrew! But that's nothing against the cabin or Karen, of course, just make sure you get your needed information before driving up.
Overall, our stay was very pleasant.
