This is our second time to stay in this hotel. We had stayed here 4 years ago as well. The restaurant is decent and we loved the great hospitality there.
The public bath is awesome and it is open til 1 am. There's also a little shampoo bar where I can pick my favourite shampoo.
The hotel room is spacious and there's a little balcony. The location of the hotel is very convenient while you can enjoy the tranquility at the same time.
One down side about this is that there's a City Tax charge for Kyoto so we need to pay extra for when we arrive. Not a big money but I would suggest to put in on your website/when the booking is made so that it makes people feel smoother when you ask them for money during checkin (I saw a customer got really angry and grumpy at the check-in counter).
As for the free drink at the north wing, it has a great variety. It would be perfect if they can have regular re-fill when some of the drinks, e.g. chocolate, is run out.
I've booked for 2 rooms and sent a message to the hotel that we hope the rooms can be next to each other/ having connecting room. However, the hotel obviously didn't pay attention to it at all:(
Overall, my family enjoyed the time here and would love to come back another time.
