静 replies messages very promptly. The unit is well maintained and neat. Good for 2 persons. Replaced faulty hairdryer quickly. Instructions to apartment is very clear and check-in process was smooth and easy. Location of apartment is great! Lots for eateries, minimarts and a 24h Dondonki within walking distance. 1min walk from Higashi-Shinjuku station and 10mins walk to Shinjuku station. Enjoyed my stay very much!
