Kevin's apartment is as described. It's a shortish walk to the train which is only one stop to shinjuku which was really handy for us for day trips out of the city. It's super quiet and comfortable at night with a quality air con unit which is really quiet and doesn't blast out icy air like most I've used in the past.
We needed an extra child's bed and Kevin brought over a single sofa bed and was really helpful with sending links to restaurants etc. Everything in the apartment is new so it's all spotlessly clean. It's also helpful to have toiletries provided as we were travelling light! Yes it's small but it's Tokyo so that's to be expected.
