Kei and his house are wonderful. It's my second time stay here. I still feel very comfortable and exiting like the first time. The rooms are clean, neighbors are quite, many facility in the kitchen and high speed portable Wi-Fi... I got totally recover after get into tatami room at the end of a busy day. Kei is so nice. He helps me a lot during the stay. We already became good friends. Kei's house always my first recommendation for the people visiting Tokyo.
