Good placement, really helpful and welcoming hosts. The room isn’t that spacious especially with the second bed out and suitcases but it’s good enough to be comfortable and it’s clean.
There are lots of restaurants nearby, sushi, Chinese food, Japanese food etc., as well as konbini.
The room is 15/20 minutes away from shinjuku by train and around 180¥ so it’s a pretty good deal! Last train from shinjuku is around midnight, and you have your own set of keys.
Just know you’ll be living with the hosts so you will see their stuff around the place.
