It is located at Gozo Station, one stop away from Kyoto Station by the subway Karasuma Line, and takes about 15 minutes on foot.
On the day of check-in, I went to leave my luggage, but the staff did not came out even after waiting for a while, so I had to return to Kyoto Station and use the coin locker.
However, when I came back in the evening, the staff was very kind, and the facilities were generally clean. But because the room is small, I can't pass by if someone is organizing their luggage. and the lounge is not that spacious, so there are not enough seats in the morning or evening to night. Bread and jam are served for breakfast.
