The house that housed the airbnb was adorable! Shohei was great! I was only there for one night before I moved to join my family at a hotel, but I wouldn't have minded staying for longer.
It's about a 10 minute walk to the station. I used a combination of the maps that Shohei helpfully provided and googlemaps to find it the first time, but it's a straightforward walk after that. There's loads of shops and food places along the way, and it is in itself very close to Shinjuku without the crowd.
It was a good stay!
