If your a couple that eats out and spends all day out, this apartment would probably be fine. As a family with a young fussy toddler we wanted to do some basic cooking for them as they wouldn’t even taste many of the things we would eat in Japan; however, the unit is not equipped for cooking apart from maybe boiling an egg.
The train line was directly outside our window so not recommended for light sleepers.
The unit was indicated to be one unit with 2 bedrooms but was in fact 2 separate very small one bedroom units. We were a family of 5 travelling together and if we’d had more than 1 young child with us it would have been a real issue.
There’s no table or chairs so if you want to eat in the unit it has to be either on the bed (not ideal with a toddler) or on the floor which is where we ended up eating.
The unit was clean when we got there; however, no one removes your rubbish or replaces towels so I would only recommend for short stays. Whilst there’s a washing machine it is very difficult to get clothes dry as there’s no dryer or balcony to hang them on (and our clothes and towels ended up smelling musty from being damp for so long as we couldn’t get them dry).
Overall if you’re a couple that will spend all day out sight seeing and eat out all the time then the unit would probably be fine; but for anymore than 2 people and particularly families I do not recommend the apartment apart from maybe an overnight stop before flying out.
