Very clean, close to the centre but away from the noise.
Our check in and check out process was very smooth and without need for any assistance.
We truly enjoyed the great apartment comes with lots of utilities, which turned out to be better than what the pictures indicated.
The place is located in the main Shinjuku area which makes it very convenient to access the central district as well as other parts of Tokyo. Main Shinjuku train and bus stations are 10 minutes walk and Higashi Shinjuku (metro) train station is just around the corner. Convenience stores including Family Mart and 7 by 11 stores are next door.
We loved the apartment and would highly recommend.
