This hotel is one of the best I ever stayed in.
From check in to check out, I never had a bad experience whatsoever.
The room was really clean and tidy, the bathroom is huge considering this is Japan. The bathroom even had a decent sized bathtub.
Since we were a group of three, one of us had to use sofabed, but that sofabed was really comfortable too.
Though the hotel itself is a bit walk from the subway Marutamachi station or any CVS, Kyoto Old Castle is just the across the street.
Breakfast was fine. They served a small Japanese salad, croissant, and small roll, and drink of your choice. The choices were coffee, black tea, or orange juice. For the salad, the dressings choices were pepper, carrot, Italian, or sesame. All of the dressings were nice. Though croissant was really buttery and hot, the roll was not toasted. It would be nicer if they toasted the roll too.
Although they have a coin laundry on the first floor, the dryer is not that efficient. I used that for an hour, but my laundry wasn't completely dry.
However, all those complaints are very minor. If I have any chance to visit Kyoto again, I'll definitely choose this hotel.
