Our stay was good. Host was very promt and guided us well. Communication was good. Honestly it is a very cheap option in Tokyo next to Kinshicho station. You can book it if you are looking for a place to just crash for the night.
To be realistic, rooms are very small. Not suitable for 2 adults/couple in one room..space wise especially if you have big luggage like us.
If you are someone who can adjust such conditions, then go ahead! Definitely value for the money!
