The place is located around 10 minutes from the next JR station and also from the Airport Limousine station. So if you are searching for a really convenient place, I hightly recommend Chiakis place. Please note, that the apartment is located on the top floor of a high building, so if you are afraid of heights, you might have some problems with washing your clothers and getting them dry again, since the washingmashine is located on the balcony. The apartment itself seems to be a bit older, so don't expect anything too fancy.
Also be aware that it can be a bit noisy at night, due to high traffic. As typical for older japanese apartments, it will get cold inside during autumn/winter. The aircon does have a heating fuction though.
But if you are looking for a convenienc located place to stay, which offers you a lot of space for a low price, Chiakis place would be perfect.
