Katsuomi is a great host, he picked us up at Oji station upon our arrival and explained us everything very clearly.
The house may appear far from the main Tokyo attractions, but with Oji station at 10 min walk, one can reach basically everything very quickly. The neighborhood is very quiet and nice.
We had a small apartment for ourselves with a bedroom in traditional Japanese style ( even bigger than expected) and a living room with a kitchenette. We had exclusive access to toilet and bathroom too. Overall the apartment could have been a little cleaner but we had a great experience nonetheless.
