Ko's accomodations were great. Close to the heart of Shinjuku, with easy access to Shinjuku Station, the room was quiet and comfortable. Ko was always in communication before checking in, and I didn't need to contact him while staying there. The place had everything I needed and more, with all of the modern amenities (especially for an American who isn't used to such features). I traveled by myself and the unit was perfect for me. I'd definitely stay here again.
