The apartment was absolutely tiny. There was no space for our luggage. The sleeping area wasn’t even wide enough for the mattress that the put on the floor. The mattress itself was very thin and extremely uncomfortable.
The communication wasn’t very smooth either. It was like communicating with a chatbot. I had to answer the same question three of four times.
I would not recommend this place. The location is great and it is very clean like everything in Tokyo, but if you’re looking for a place to sleep for longer than a night, pick something else.
