The neighbourhood is lovely, the Yamanote Line and the Subway are a short walk away, the price is low, and it's very clean. The rooms are very small indeed, check-in is open only until 6pm (you have to call a staff member down via a courtesy phone if you arrive after that), and there are no frills. It's a bit faded, and the washlet in my room didn't work, but for the price it's decent value as long as you know what you're getting: it's a weekly residence rather than a hotel, so they're not going to come in and make your bed every day. If that bothers you (it doesn't bother me), look elsewhere.
