I'm considering Toyoko Inn bcos i liked their Shinagawa location. Haven't stayed before and not sure if I'll stay again.
Maybe I should just keep checking back on booking.com if I don't want to get the membership just for the 6-mth advanced booking.
But still considering other hotels also. Shortlisted Sotetsu Fresa Inn and some others for Tokyo. I really liked Shinagawa Prince but it seems that their November prices are rather high.
Dormy Inn's Harajuku branch I don't quite like. Not that cheap and the cheapest room damn small. Location far from train station and hard to find as well.
I wouldn't use booking.com. I would go straight to rakuten or jalan website. They have better deals.
