It was generally a wonderful stay in the cookie house. The room is the same as shown in the picture. Location is good. Only 5 mins walk to the subway, and 15 mins to the center of Shinjuku. And the bed is a huge plus! I usually feels pain on my back with a new bed or mattress. But I didn't have any problem with the cookie house bed! That's amazing!
As for the noise, it's actually not bad. I am a light sleeper but the sound didn't really bother me. With a whole day touring around I am usually exhausted when sleeping, so the noise didn't wake up during the night.
We were a team of four. So three chairs in the kitchen is a little inconvenient. The room is clean but not as clean as I expected. Overall the place worth the price. It was a wonderful stay.
