LOVED IT! What a fantastic place with so much space considering its location. And it's in the heart of Shinjuku, so handy to the Shinjuku train station, loads of places to eat and shop. Hosts were friendly and kept there place in excellent condition. I would stay there again in a heartbeat, without hesitation.
Note: Beds are very comfortable but, if you prefer a soft pillow, you might want to bring your own.
