We came from Osaka by shinkansen and arrived at the JR Tokyo station, which was very far from the hotel. The subway will come in handy for trips to Central Tokyo and other far places in Tokyo. However, nearest subway stop (Toyocho on the Tozai Line) is still about a 7 to 10-minute walk from the hotel.
Rooms are big, spacious. Beds are a little small but comfortable. And they come with two pillows! The A/C in the room was quite warm though. Best to call housekeeping and have it fixed.
Bathrooms are a little small but serves its purpose. It also comes with its own pump container for shampoo, conditioner and body soap. They're very generous when it comes to towels.
Staff are quite helpful but there are still a lot who cannot speak English but can only understand. It's best to talk to the Front Desk staff or the Asst. Manager if you need something.
East 21 Tokyo is also a Disney partner hotel so shuttle to Disney Resort is free. Best to reserve as soon as you arrive at the hotel because shuttle tend to fill up quickly in the morning. They also provide shuttle to the nearest subway station but you will have to make reservations. Shuttle reservations can be made with the concierge. Airport limousine buses also stop here so it's pretty convenient if you don't have a ride to and from the airport. Although if you're leaving very early in the morning, it can be a bit of a hassle (which we experienced) since the first trip leaves at 7:30 in the morning.
Our reservation didn't include daily breakfast but we didn't worry because there are several places that serve breakfast right outside the hotel. And there are other breakfast places in the surrounding area. There is also an am/pm convenience store outside the hotel, where you can get lots of cheap breakfast items.
It's a pretty good hotel, not my first choice since I would have preferred staying near Central Tokyo. But if you prefer a quieter place that's still near Central Tokyo, then I would recommend this hotel.
