Apartment was in a good location and condition - close to Nishi Shinjuku office areas and Shinjuku Central park. The owner was accommodating, gave us a replacement wifi device, dishwashers rack, offer us for a baby cot and gave us some flexibility for check in and check out time. I did not give it a 5-star simply because I feel that some of my messages were not responded to - I have to remind them to reply. That lack of response did not interfere too much with my stay though. I would recommend this place
