Mami is a very nice host, always available & the place is 2 minutes from megurostation, where you can hit to everywhere in Tokyo. As well they have a lot of restaurants & a supermarket in the area. Mamis frat has everything you need (coffee, tea & you can cook a ramen soup there or something small in the little oven). Everything is super clean & the door is a safety look door, which is cool if you have expensive items :)
P.s. watching Japanese tv there at evening was a lot fun
