Yoshimoto's place is wonnderful!
We stayed there a whole week and I could have asked for a better place. Matress where confortable, room very clean and enough space for two people with a big suitcase each. (even a couple with a little child could fit)
Location was the best part, we where walking distance from Asakusa Senso-ji so you can go every morning and specially every night with all calm!
There'se also a big store (Don quijote) where you can find anything very convenient and is surrounded with traditional restaurants opened until very late.
I recommend to stay unless you are in wheelchair because of the stairs but otherwise, dont look other places, stay here!!!!
Yoshimoto is very kind and flexible and he provided us with pocket wifi (requested previously) shampoo, etc... Also he answers airbnb messages very quickly.
