If you want a nice and simple place to stay in a good location, this is the place. The host and staff are also very accommodating and helpful with their knowledge of the local area. The room has enough space for two people and the bathroom, while compact, is useable. The metro station is literally 1 minute walk and the main Shinjuku station is 15 minutes max (10 minutes for my wife and I). Shinjuku itself with the main shopping and restaurant area is 10 minutes walk max.
Would certainly stay again.
