Kotaro and Kei are fantastic hosts!
They help me with my tic at Ghibli museum.
They give me a complimentary portable wifi hotspot to use around the city.:)
Once I got lost (google fault ;)) and they helped me and find me 5block away in the night!!!
The room was big and the bed was so comfy, but I love the most toilet designed with Totoro carpet <3. Their place is very close to mrt and JR line which is very, very comfortable to travel around Tokyo.
