The ANA Hotel Kyoto is approx. 10minutes by car from JR Kyoto station and one minutes walk from subway Tozai-line's Nijojo-mae station. There is a free shuttle bus from JR Kyoto station to the hotel:

Use this directory to assist you and make sure you have prices that are as good as these discounted levels, which are generally cheaper than hotels direct. Your agent might be able to book online and charge you a fee for doing so.
