Mor's place is really good. It is unbelievably spacious for a Japanese home. It's got cooking essentials for making breakfast or quick meals. Every room is equipped with a modern AC - though we rarely had to use them. The futons and tatami mats are really nice -- not only do they give an authentic Japanese feel, I think they're also good for people with back problems. Oh and all the rooms have lovely sliding doors that add to the traditional Japanese atmosphere.
The location is good too. There's a Family Mart convenience store, a department store (with an electronic/appliance shop above), plus lots of restaurants and cafes -- all within walking distance. The neighborhood is quiet, so be sure to abide by Japanese customs and avoid making a lot of noise. Neighbors are very nice, friendly and helpful too.
The area is highly walkable and you can reach Ohanajaya Station in less than 10 minutes. From there you can go to more central places like Ueno, the Skytree and Ginza in less than half an hour. Needless to say, the transportation system in the city is amazing -- fast, efficient and reliable.
I had a feeling that Mor's place would be amazing so I rebooked it to spend my last days in Tokyo there -- and I'm so glad my hunch was right.
