We have stayed for 4 weeks in this place. For the price we paid, I'd expect the place to include more amenities, but it didn't. We had to buy our own glasses, utensils, bowls, chopsticks, etc.
The fridge was tiny (it's a minibar, not a fridge), which made our long stay quite challenging.
The beds were uncomfortable and our requests to change a mattress were rejected, so we had to buy our own air mattress. The bedding was cheap that I suppose you throw away after one use. So we also needed to go and get our own bedding. For someone who's coming to stay for longer than 2 days, I'd expect the owner to provide a better quality bedding.
The flat should have its own vacuum cleaner and an iron, but they had to be shared with other flats in the building. Most often we couldn't find the hoover as the other residents were not returning it to the station, which led to our flat become quite dusty over some time. The property doesn't include any cleaning services either.
On a positive note, the location of the flat is quite nice. It's close to the Imperial palace for daily jogging, Akasaka high street for easy shopping, convenience store and the station few minutes away. The owner was responding to us promptly. The flat itself is nice and new.In general, I'd recommend this place to anyone coming for just a few days, but not to rent for longer than that.
