Pros: location is perfect (very central), beds are decently comfy, has a balcony and WiFi felt quick enough. Decent value for the money if you just want storage, a bed and to be central in Shinjuku.
Cons: the bathroom, especially the shower. The vent in there needs to get fixed as there is visible mold on the ceiling from people taking hot showers and regulating the water temperature is an issue to say the least. Overall a typical small hotel room type layout and you're ultimately paying for the prime location.
