Incredible location, helpful staff, great style throughout, excellently comfy bed and REAL PILLOWS (which are apparently hard to come by in Japan..) I stayed in a few of these smaller, boutique style mid-range hotels throughout my trip and this was my favourite accomodation by far.
For me it was just the little details; the welcome box, the magnet housekeeping system, the additional blankets/heating for the colder week, bottled water in the fridge, the embossed notepad on the desk - everything was just exactly how it needed to be.
If you have any love of design, interior decoration, brutalist architecture, or just want to be 30 seconds away from beating the crowds to get "that picture" on all the travel blogs - this is your place.
