My partner and I had a great time at Villa Johanne in Port Renfrew. We didn't spend much time at the cabin as there were so many beautiful places to see - all easily accessible from Mike's place!
The cabin was very clean with a comfy bed and couch.
The only advice I would give would be to bring your own groceries - we neglected to look into what Port Renfrew had to offer. There is a only a small corner store. BUT we had great meals at Tomi's and at Renfrew Pub :)
Can't wait to visit Port Renfrew again.
