We chose this hotel because it was really close to the airport and the theme looked cute. Our kids loved the check in service. It's done by three animatronic characters and is contactless. Some people complained the process was complicated or didn't work but we had no issues. Check out was simple. There are good vending machines with beer, ice cream, sim cards, and cosmetic kits. They have a manga library you can borrow from. There's a Google Chromecast in the room so you can stream TV from your phone. The English instructions to all the electronics was very helpful. We did not use the airport shuttle because we heard it fills up fast and the train station was only 5min walk away and a 10min ride to the airport. We didn't get a chance to try the breakfast. There are plenty of good places to eat nearby within walking distance. The rooms are small but we fit 4 people in the three bed/one pull out bed and it didn't bother us for the one night we stayed. My only complaints is the bathroom needs a stool to shower on and some nooks and crannies could use some more scrubbing. Our toilet seat was also cracked. I'd stay here again as an easy access to Haneda airport hotel.
