Staying in Hiro's apartment was a great time. It offers a very realistic experience of Tokyo living with it's cozy main room and miniature kitchen and bathrooms. The Kamata center by the station is plenty busy for the area and is teeming with delicious authentic Japanese food if you are able to crack the language barrier ;)
The station is also really easy to maneuver and isn't too far from the bigger city centers like Shibuya, Ginza etc.
If you're traveling with at most three people and want a modest and comfortable place to stay, this apartment will treat you really well!
