I don't want people to know how lovely this apartment is. As it is going to be very difficult to book this apartment again in the future, I would come back again in a heartbeat. It felt like a second home, had the perfect location with beautiful views, very close to multiple shops and train stations.
As a 5-minute train ride out of Shinjuku and direct train links to Akihabara, you wouldn't expect the neighborhood to be as quiet as it is. The apartment is probably the nicest place I have stayed at using airbnb.
