Helpful staff (although they don't speak much english), laundry on site for 200 yen (wash+dry), multiple konbinis (7-eleven, Lawson, FamilyMart) within walking distance, and very close to Yamanote Line train station which connects pretty much all you would want in Tokyo.
The biggest issue was the condition of the rooms, and some details about cleanlines. Mold in the bathroom, tiny stains on bedsheets, wallpaper tearing off in some corners, and holes in the walls.
I wish the hotel cared more about solving all of these. Overall: Not great, but not horrible either.
