We have stayed at this hotel on a number of past trips. It is in a great location - very near JR Ueno Station. Most of the staff is very friendly and helpful. Although the room is on the small side, it is clean and neat. The cleaning staff was very good.
I'm not sure, but it seems to be a hotel for business people who return to their rooms late at night. It can get quite noisey as they bid each other good-night and enter their rooms.
