The location of this studio is very central: about 12 min on foot from Shinjuku station (JR), 9 min from shin okubo station, and 5min from seibu Shinjuku. There are also other stations within 10 min walking. We did a couple of day trips out of Tokyo, so staying here was very convenient. Being in Shinjuku, there are hundreds of shops and restaurants close by, though the location is near a small "park" so it still feels quiet. The studio itself has 2 full sized bed with fluffy comforters, and small kitchen (with a stove, fridge, microwave, water boiler, and fish grill), a room for the toilet/bidet, and a room for the bath/shower (the bath is automatic!) and washing machine. Shampoo, conditioner, body soap, a hair dryer, as well as laundry detergent was generously provided. There's also a small balcony, which we used to hang our laundry to dry. Overall, the studio was very clean and comfortable for the two of us. It could technically sleep four, but I could imagine it being a little cramped. As far as communication goes, we received very detailed directions and check-in/out was seamless. I would definitely recommend staying here!
