My family of 4 stayed in the Annex and it was certainly beautiful and very conveniently located - but wow, it certainly was an expensive experience for us (especially in April at the end of the Sakura season). Traditional tatami mat floors in the rooms with futons were great for the kids, but I was very pleased to utilise an extra foam base that was in one of the cupboards to provide just a bit more padding. Still, a lovely space for our visit, great location to utilise transport options, a traditional experience to mark off the list, and a park across the way that was great for the kids to lose some energy in.
