Everything was good in the apartment! We really liked how clean the apartment was and that even the sleeping couch was made up already. To our pleasant surprise there were even some toys for the children to play with. I don't have anything which could be improved actually.
Other utilities like the wifi, chrome-cast on the TV and dishwasher were really nice!
Also the little details like the Japanese things in the house and the paper with instructions and some pointers for in the city were really nice! It was nice to see that based on the house you could almost tell what people are living there.
