Mr. Kuni is responsible host which quick reply always, and did couple of advisements to my needs and questions.
The room locates close to Hamatsucho station as described with 5mins walk. However, the JR station is not very friendly to who has many belongings together with because no direct escalator/elevator to the ticket lobby, but that is not the problem of Mr. Kuni. A courier service point (yamato) is just locates around with 1min walk, so that i can arrange my baggage to airport conveniencely to reduce my barrier. This helps me a lot!
Well, about the room, all the basic equipments provided functions well. And cleaning is done on time for check in, but it will be perfect if the mattress amd the pillow which are better support the back could be changed and provided.
Overall, it is a satisfied experience during the stay at Mr. Kini's place. And I do definitely to stay again if I use the Haneda airport.
