The apartment is located only a few minutes away from the heart of Shinjuku. There are stations for Shinjuku and Marunouchi line a short walk away and Shinjuku gyoen is also within short walking distance.
Although the apartment is located in the center, it is super quiet.
The next larger supermarket is just around the corner, but there are of course also several convenient stores just across the street.
The apartment itself is great- I spent several weeks there and it really felt like being home. You will find everything you need in the kitchen, the bed is comfortable and I enjoyed the whirlpool function.
Check in was also super convenient, there were absolutely no problems. I would definitely return to this great place and recommend it to everyone :)
