We were a family of 6 and paid $330/night for 6 nights. We loved the location and layout.

We didn't expect the onerous advance registration. Ruka manages the property remotely and required that I complete 6 forms and upload copies of passports for everyone (including our minor children) onto their website. I asked her if there was any other way (e.g., provide the information in person), and she apologized. She's not around. Other hosts try to accommodate, and request only the main registrant's personal info. Not Ruka. I asked her to delete the uploads after we left, and she said she would after 3 years. She assured us the info would be safe.
The beds were comfortable, but not the thin/old futon (subpar) for our 6th guest. He couldn't sleep. Ruka's response: we could bring in another futon on our own, so long as we took it on with us when we left (WHAT?).
After our stay, she asked us for a 5-star review.
