Cute and clean place, with plenty of room and everything I needed. Comfortable beds and good air conditioning. Relatively close to the subway station and to the activities in Shinjuku. Door lock is easy and efficient. A close walk to the Royal host family restaurant for breakfast. And money can be changed in the hotel lobby next to the Royal host. Very convenient. Kind people operate the restaurants around the block and everyone is happy to see you in the mornings.
There is a hospital nearby however and the ambulances are quite noisy and they go by incessantly. This is the one negative, otherwise the place is perfect.
