The apartment is very clean and the people who manage it have been very helpful to our every request! The beds are large and soft, the specific because in Japan between futons and narrow rooms (my husband is 1.93 tall and the brother 1.95) is not something to fly over, so arrived in this apartment we had some good sleep .
The only flaw of the apartment is the bathroom area not separated by a door, otherwise everything is perfect, the common spaces are clean and comfortable, the dishwasher and the washing machine were very useful for us. The underground is near 10 minute so getting around was pretty, although Tokyo is a huge city.
Very satisfied!
