Chonglin responded almost immediately to each question as they came up. As we arrived a bit too early for check-in, he allowed us to store our bags in the apartment for a few hours, which was extremely helpful and truly appreciated. Apartment was spotlessly clean, and with very nice and clear weather offered a wonderful view of Sky Tree. A short walk between the apartment and Naka-Okachimachi train station (we mainly used Hibiya line). Highly recommend staying here for comfort and convenience. Thank you, Chonglin!
