I had a good stay overall at Nestay. Room was well equipped with kitchenware, furniture, and strong AC. Everything was as on pictures so no surprise. Supermarket and 24h convenience store in 10 seconds, and JR mikawashima station in 4-5min. All inquiries handled promptly and kindly.
The only minus was slow internet at night as speed slows down to 1-3 mbs with ping 60-80ms. It was steady and fast daytime.
