"Super convenient for catching early flight out of Haneda. While my flight was from Terminal 2, and this hotel is connected to Terminal 3, it took less than 20 min the check-out and arriving at Terminal 2 in the morning. There will be some walking required through Terminal 3 to get to the hotel, and a shuttle bus to Terminal 1 or 2. Still, it was well worth staying within Haneda airport compared to taking a bus or train. I stayed Grand, not Premier, and even though the lobby of Grand looks nice, the room is basically a nicer business hotel. Still clean and very functional, but not much else.
Breakfast, it is very pricey. And for the price, I thought it would be better but it wasn't. It was quite disappointing. First, coffee is another "press a bottom" machine coffee. For that price, and a hotel like this, I would wanted to have a freshly brewed coffee. Breakfast menu is large but everything I tried (except bread) they were nothing special. It is as if they are going for quantity rather than quality. So skip breakfast and go to a convenience store nearby."
