"+" are good points, "=" are neutral points of interest, ">" are negatives for me.

International Garden Hotel Narita
+ Room was decent in size
+ Free shuttle from Airport
+ Staff spoke English and volunteered information freely on transport
> Isolated, this is really a transit hotel (as in you're only here cos you're on your way elsewhere.
> In-house restaurant was about the only food option
> Buffet dinner at Y2200 per person was pricy.
Hotel Route Inn Abashiri

+ Shuttle bus from Airport - Y840.

= Staff could understand enough English
= Japanese style common bath (not of interest to me).

Kyoto Garden Ryokan Yachiyo Hotel
+ For a traditional Japanese Ryokan experience
