I had a decent stay at Norio-san's place. It was exactly as pictured, and a comfortable futon for a very good price.
Kiki the cat was very fun to play with, but got cat hair everywhere. If you don't like cats, you may not enjoy that part. I love cats, so it was fine. I needed a lint roller though, I had to buy one after leaving.
Check in and check out times were according to when Norio-san could be home. Unfortunately for me, he had to work late, so my check in time ended up being rather late, and I had wait around Shibuya station for a few hours, exhausted. I had already booked before I knew the check in/outs times. It's probably a good idea to message him about those first before booking.
Norio-san was extremely friendly and welcoming, and eager to practice his English. If you need a place to stay for the night, and want to chat and play with an adorable cat, I recommend this place.
