This is a great spot to stay for 1-2 people when visiting Tokyo. Ohjiro's place is clean and has all the amenities you need – clean bathroom, shower, A/C in the summer, and a little fridge and kitchen area. The bed is very comfortable for one person, for two people it might be a little tight but manageable.
It's accessible by subway and in a nice neighborhood. There are lots of restaurants nearby, as well as a great coffee shop called Counterpart Coffee Gallery. There's also a FamilyMart and 7-Eleven nearby for late night needs, which I found convenient to buy water at.
Ohjiro is communicative and if there are any misunderstandings, he works with you to resolve the issue.
