Very good place to stay, although could do with some better english translations - The two nearest stations are E30 and E29 (Nakano-Sakaue and Nishi-Shinjuku-Gochome), if you are following the directions you should go from E30, Exit 1 and then take a right AFTER the vending machines not before. Overall really nice place to stay would stay here again, good location. Just wish there were english instructions for how to use the washing machine and air conditioning, although took about 10 mins to figure out :) Internet speed was 500mbps which was nice. One of my friends left the shower tap on by mistake which cut our gas out for a day, we managed to figure out how to reset however. At the front of the house there is a gas box with blinking red lights, you just need to push the button until the blinking red stops and the gas is restored.
Thanks host!
