We had a wonderful stay here! It's a very cute place, well designed and equipped. The host was very responsive. It was nice to have two bathrooms and a spacious living area.
The neighborhood is very cute, with lots of little local shops and restaurants nearby, as well as convenience stores and markets. Even with the shops and restaurants, it was surprisingly quiet. We heard sounds from the street a couple of times, but it didn't disturb us. The Sasazuka station is a short walk away, with some larger shopping options and tons of restaurants there as well.
A couple tips on check-in:
-Shinjuku is a short train ride away on the Keio line, but note that transferring to the JR lines can be tricky. Best to ask station staff for directions.
-Checkin is all self-served. Fill out the online form before arrival to get a "checkin code". On arrival enter the code on the tablet (not the door!). Then take a selfie with an ID on the tablet, after that you'll get the door code to unlock the door.
