Nicely located in a lively Korean district in Shinjuku. About a 10 min walk to two different train stations, and a 5 minute walk to a nearby coin laundry. Coin laundry includes detergent with wash, and is 24 hours.
The pillows were a bit rough, but the place is fairly well insulated and cozy. Though you could probably stuff a lot of people in this place, the only thing to worry about is that there's only two sinks available. :) Zenia is fairly prompt at responses.
