First of all the pros: The location of this place is great. Okubo station is right outside the door step. (Literally right outside the door) It’s one station away from shinjuku where all the action is. It is also walkable to shin-okubo station. There are lots of convenience stores around the place and walkable to lots of restaurants, cafes etc. There’s also a Korean-street 5 mins walk away. We stayed with 4 adults and 2 kids and it felt just bout right. As expected, the space is pretty tight but generally clean and well equipped.
Cons: as it is so close to the train station, you will hear trains passing in the house. After a while it does becomes a background noise but if you’re a light sleeper, it would be a problem. There is also no portable WiFi as advertised. As this is a 2-storey place, the WiFi on the second floor is very weak and non-existent. There are also sewage smells occasionally from the bathrooms.
