... and don't fit in a capsule hotel, this is a great place to stay.
The hotel is in a narrow-street neighborhood, but Google maps works. I took the Airport Limousine to the Tokyo City Air Terminal (TCAT), and walked both ways - it's about 2 km, and very safe. I checked out at 5 am and was completely comfortable walking back.
The room was small, but laid out very efficiently. I needed more electrical outlets (if you unplug everything, there are two in the bedroom and one in the bathroom), but I had a multi-outlet extension cord, so no problem.
The bed was a mattress on a platform, but was very comfortable. The desk was very usable, given that you sit on the bed platform (no chairs).
If you don't read Japanese, ask for help with temperature control. I guessed how it worked, but I was guessing.
The staff was incredibly friendly, with enough English for all the conversations we needed to have.
I'd definitely stay here again, and I'd look for other highly rated two-star hotels if I wasn't in this part of Tokyo.
