Communication with Shohei was easy and pleasant due to his English proficiency. He was quick in responding to messages which was very helpful and reassuring. As for the studio apartment, it was great for the two of us. The fold-down sofa converts to a bed which we found very comfortable when made up with the provided mattress pad and bed linens. The kitchen was small but well-equipped with a stove, small fridge, electric kettle and rice cooker. We also have to mention that the apartment was absolutely clean and spotless. The neighbourhood is in a quieter residential area several minutes away from Shinjuku Station by train on the Keio line (Sasazuka Station). We were also pleasantly surprised with the array of nice shops and restaurants in the area. Very convenient if you don't feel like dealing with the crowds at Shinjuku. The host is super nice and will provide recommendations if you ask! We stayed here on our last night before going home and it served us very well.
