After landing at late night in Haneda Airport, and loosing the last bus to the city centre, i decided to look on Internet for an businness hotel in the Shinagawa area and get there by taxi. (only about 10 minutes and 3000yen)
The receptionist has been very polite, and explained me all the room types that were avaible at that moment (was 1:30 am!)... ok, i was lucky that i can speak some japanese, but he has been very kind.
I stayed in a single room (about 5000yen). The room was really clean like the bathroom. As every biz hotel you are given also a pajama, a toothbrush, razor and so on... ;-) Inside the room there are also free tea/coffee making facilities.
On the following morning i easily got my way to the station (there are 2 within a couple of minutes)!
Good value for your money!More
