We enjoyed our stay here, it's a very small room but it has lots of amenities, including a shower and bath, toilet, washing machine, microwave, fridge freezer, sink, and two gas hobs. Check-in was very easy. The area is really cute and quiet, and very well located for travelling in to the city centre or to Shinjuku station.
The shower is very small so if you're taller than 6ft you may need to kneel in the bath.
Would definitely recommend as a great place to stay.
