I really love this place! it's a little pricey for us since there is only 2 of us. but I can imagine staying with your family.
it have 4 beds and area you can set up futons.
we have everything that we need and more. a small kettle to boil water, kitchen and utensils. the bath tub is small, but still comfortable.
the host very quickly sent us the instructions to operate the controls for heater, TV, trash when we inquired.
and the balcony is just fantastic! Because of the cold and windy weather, we did not get to enjoy it the fullest. But the hours we spent enduring cold fingers is worth it, to take shots of the Tokyo city, the Skytree, and even Mount Fuji !
the location and neighbors is really nice. close to the Yamanote line, and the quiet Fabric Street is really ideal.
If you already expect to walk a lot in Tokyo, the distance to Nippori station is quite convenient. If not, you have to expect a 8mins walk.
All in all, love it! Thank you!
