We had a great stay at Stayme Hotel. It is very accessible to public transportation, just 1-2 minutes walk outside the Iriya Exit of the Ueno Train Station.
The place was clean and modern and had adequate amenities for 4 people.
The host was very responsive to queries and helped us with check-in. They have a self-check-in and out system.
I highly recommend this place. Thank you, Stayme!
