Good location close to main Shinjuku station. About 10 min walk east on the street, less if you walk the underground path (recommended if you are not street shopping - you can bypass the streetlights and walk faster). 2 min walk to the Shinjuku 3-chome underground station. This was the entry we used the most. Very convenient. There is a Shinjuku line that runs to main station if you don't want to walk. Just 1 train stop.
Room is extra clean and modern. Laundry washer is inside the room, and the best part is that the shower/bathtub room can be used as a dryer (you hang the washed clothes). This was by far the best part, since we didn't have to look for a coin laundry to dry the clothes (many Japanese washer is washing only, no dryer). We hung the clothes to dry overnight or during the day.
