I had the most amazing stay at Sunny’s! It’s in a quiet residential area and is walking distance from the subway stations. The room was very clean and the bed and beddings were so comfy. He also lends you a portable WiFi which really helped me out on my trip. Everything you need is there. Just be mindful about the room being on the third floor and going up some stairs to get to the room and down stairs to use the toilet.
Sunny is a very thoughtful and kind host and cooked us delicious breakfasts and was very helpful in providing me directions on how to get to his home.
I would stay here again if I was coming back to Tokyo :)
