Great place to stay when visit Ueno. Bigger room than standard Tokyo hotel size, and washing machine is a plus.
Please note that the check-in time is strictly 4pm, so if you have a redeye flight you won’t be able to refresh yourself until then. The good thing is, you can leave your luggage with them and walk around (zombieish) or find a coffee shop and take a nap til the room is ready lol.
