The location of this apartment is very good, right next to two train stations and in the middle of Akasaka. Lots of amazing restaurants and cafes around the area. Check-in/Check-out was also very easy and is through an automated system.
The apartment itself was modern, however, it was not cleaned properly and looked as if nobody had stayed in the apartment for a few weeks prior to our stay and it was very dusty. Additionally, the bed is not an actual mattress, but just a piece of foam, probably the worst sleep of our lives. And, the pillows were so thin that they did practically nothing. We did ask our host if new/more pillows could be provided but were denied. We just ended up buying some pillows from Donki. Do not recommend staying here if you have a bad back as the bed and pillows are extremely uncomfortable.
As for amenities inside the apartment, there are no knives, only one pan and it doesn't work (we bought a new one and left it there, so there might be a working pan now).
