Koichi is probably the best host that we've had since joined the site, he really went an step further compared to the regular host, I couldn't recommend him better he is very polity and serviceable.
The place is also very well located 10 minutes walk distance from Shinjuku station there is supermarket 2 minutes away and plenty of convenience stores around. A malfunction with the wifi device was sorted promptly that made all the difference to our trip as we relied on it to go places.
May be a stove would have been a good idea to have in the apartment.
