Good location if you're visiting Tokyo Dome. The place was comfortable and easy to find.
However, as other reviewers have mentioned, the wait for the shower was incredibly long. There were about 8 rooms sharing one shower and two toilets (one female and one male), which wasn't sufficient. Also, we had some trouble getting into our room as the host had initially given us the wrong passcode. We spent a few minutes panicking, but the host eventually got back to us with the correct code.
All in all, it was a comfortable stay for one night in Tokyo.
