I found this hotel on booking.com and due to the very reasonable price and location to Haneda Airport, I decided to book for 5 nights.
Check-in is automated and once the card key comes out of the slot, I pick up some free amenities by the elevator and take the lift to the 12th floor where my tiny 13 sq mtr room is located.
It is totally functional- everything you could possibly need is here – mini fridge, window that opens (slightly), bathtub,/shower and strong hot water comes out immediately, tv, working desk, humidifier, double bed. It’s perfect!
And to top it off, a pretty decent buffet breakfast is served daily from 6.30 to 9am.
Oh, and a bus from the hotel to Shinagawa station runs all day. Every 15 mins.
Definitely recommended if you are traveling for a short stay to Tokyo.
