My party's stay at the Asawa Family's residence was great. We were looking for a place to stay in the Shinjuku area and it was within walking distance from JR and metro stations. Walking directly into the heart of Shinjuku is a short 15 minutes away. The checkin process was pretty straight forward. There were 5 beds which was plenty for my party, but just be prepared to watch your head if you're a tall person. Communication with the Asawa family was great through the app. There's also a 7-11 a minute away from the front door, so all you need to stock up refrigerator can be found there.
