An pretty comfortable experience.
Landlady Rey is very very nice. We came to Tokyo at midnight and didn't know how to open the door..I called to her and her patiently tell us how to do.
Japanese toilet lid is awesome (can be heated, can flush your butt with warm water..hahah I love it)!! The bathtub is a bit small.Tatami room have a veranda so dry clothes very easy. Landlady provide a free pocket wifi, you can take it when you go out.Shampoo and body wash are provided.
3 subway stations nearby, but every one is not very close, it's necessary to go some distance.
But the house is very close to Akihabara, ueno park and asakusa temple, you can just walk to those place.
