Area is great. About a 10min walk to Shinjuku and 5mins to the yoyogi station. The area is quiet and close to the park. Host is very responsive and helped with arranging an earlier check in time. The shower and toilet was a bit small but we got used to it.
The one downside was the mattress, it was quite thin and so was hard to sleep on. Would be great also if the washing machine can also dry.
