We were enamoured by the layout, simplicity and of course the location- 5 minutes from Shinjuku by train? Perfect! As a party of 5 however, we felt a bit cramped in the space after some time. This was the least of our worries though. We arrived to find bags of dirty laundry and broken, abandoned luggage just outside the front door which remained there for the entirety of our stay. The air conditioner and the vents in the apartment were filthy with dust hanging from them all. Most surfaces were dusty including the floor and the bathroom where we encountered mold.
If you don't mind all this however and looking for a place close to the city then definitely go on and book but I'll definitely look elsewhere for my next group visit to the city.
