My husband and I had a great stay at Akemi's place. It is literally one minute walk away from Okubo station (1 stop away from Shinjuku station by JR line). It is also possible to walk to Shinjuku station that takes about 10 minutes. Very close to many eateries and restaurants and many of them are halal, which is great for Muslim visitors. There are four units to the cluster and we stayed on the second floor, stayers need to note of the stairs (especially if you have heavy luggage). The area is quiet at night so you get minimal disturbance. Room is spacious enough, there is a storage space that is big enough for one large opened luggage. Only grip is that the toilet bowl is the traditional flush, not your automated with bidet, so it gets cold during winter when you use it! Nevertheless we love the location and we had a great stay!
