Although I believe that this hotel is normally hourly, or nightly, stays, we stayed for almost a full week. The hotel staff was accommodating and friendly, despite a language barrier. The executive concierge, as well as Maryann, another staff member, were especially helpful. Our room was made spotless every day. The amenities were amazing (sauna and jacuzzi in room, karaoke, free adult entertainment and video on demand, lots of items and toiletries to borrow or rent, 24 hour chinese food). Although the hotel was fully booked most of the time, especially on weekends, we never heard anyone - rooms are soundproofed. We were so comfortable, happy and impressed.
This hotel is in Kabukicho, which is a nightlife part of town. Golden Gai (many small bars) is nearby. There are many smaller train stations nearby, and Shinjuku station (also a big mall) is a 10 minute walk. Harajuku and Shibuya are a quick train ride away. Overall, this area was very convenient, fun, and safe. On the weekends, it gets very busy with people partying, but on weekdays and mornings, it is quiet and serene. Highly recommend staying.
