Late flight landing with family made staying at this hotel, 10 mins by taxi from Haneda, was ideal. Very simple and small but perfect for one night sleep for our family before entering the crazy and fun times in Tokyo. You can check in at anytime with key codes. Very responsive and friendly English speaking g virtual night porter guides you through the check in process via iPad.
Very hot inside the room, the air conditioning didn't work. There's no front desk person at the hotel you have to talk to someone on a screen. Bad communication with hotel staff ! They advertised the room as a two bedrooms, but what you get instead is a very small room with a bunk bed that feels like a jail cell !
This was new one for me... a completely unmanned hotel. Check-in is done talking to someone remotely on a video screen; a door code is given to get into the hotel, and another door code to get into your room (there are no keys). The room had a mini-fridge. Instead of a TV, it had a projector and a screen. The place was very clean, although (surprising for Japan) there was a shower but no bathtub. Rooms facing the street will have some noise on occasion, but it's not a big street. A city bus goes right from in front of the hotel to Haneda Airport for 240 yen, or you can walk for 5 minutes to the Keiku train station to get into town. It's in a fairly quiet part of town, with a Family Mart across the street. Wifi is fine. Checking out is done by scanning a QR code on the door.
