Kashoutei Hanaya looks ideal for what we're after, a bit more boutique, with well rated dining options. I did look at staying in Dai-Ichi Takimotokan, but it seems more family orientated, and thought it may be a bit busy and loud for a getaway. Spending a day there would be preferable I think.

Thanks for the links, will take a look through this evening.

Am I right in saying most hotels in Japan don't open bookings until three months before? I've been searching just to research, and availability seems patchy at best.
