Stayed 3 nights and had a great time. We were lucky as our stay coincided with one of Hisao's "beer parties", where his fellow Kendo martial artists stay for dinner and drinks - great way to meet local and super friendly people. We also tried a kendo lesson where Hisao taught us basic moves - definitely a highlight for us as it was a real cultural immersion.
The room itself is according to pictures and other reviews. Not fancy but comfortable enough, with Wi-Fi and a good shower. Very clean and quiet (apart from kendo times 10-12 and 6-8pm).
Hisao is a great host - he was accommodating with our check in time.
Location was good for us as it's a walking distance to Ueno Park and the JR train line. Easy access from Narita airport as well.
Overall very good value and a very enjoyable experience. Thanks very much Hisao!
