Everything at Yasu's place was perfect for our trip, and Yasu was great too.
We stayed at his place for a week, 2 people, which worked very well. The kitchen even has everything you would need if you want to cook for yourself. Yasu also provided some tea, snacks and water for us, as well as everything we needed in terms of bedding, towels, toilet paper and shower supplies.
Yasu even picked us up at the station and showed us to his place, and on the way he pointed out some convenience stores and nice restaurants and shops on the way. It's a 6-7 minute walk to his place from the station, so very convenient for getting around Tokyo.
All in all it was a very pleasant experience and I would, without a doubt, stay at Yasu's place again if I ever come back to Tokyo
